Conference hotel room demand is measured in several different ways: booked events, total rooms, room nights, peak-night requirements, attendees, and hotel occupancy. Recent destination reports show substantial demand, but the measures are not interchangeable. This guide keeps realized room nights, future bookings, tentative demand, and forecasts separate so event planners can use the figures appropriately.

Recent citywide demand
Destination convention bureaus report strong citywide activity when large events draw attendees across multiple hotels. Philadelphia recorded 267 total booked events in 2024. Of those, 21 were classified as citywides requiring more than 2,000 hotel rooms on the peak night. The city’s 2024 booked events drew 542,202 attendees and generated 581,612 hotel room nights, according to the Philadelphia Convention and Visitors Bureau and Pennsylvania Convention Center Authority 2024 Annual Report.
Anaheim’s 2024 figures were presented as a projection rather than realized annual production. Visit Anaheim confirmed 148 conventions, meetings, and events for 2024. Those events were projected to welcome more than 947,000 attendees and contribute 610,000 room nights in local hotels. Because these are labeled projections, they describe expected demand for the 2024 event calendar, not a final consumption total. The figures appear in Visit Anaheim’s 2024 destination announcement.
Atlanta reported more than 800 conventions and events hosted and booked through its convention bureau in 2024. The destination also reported 1.5 million room nights booked in 2024 for future years and hosted 21 major citywide events during the year. These numbers combine events already hosted with bookings for later years, so they should be read as a sales-and-production snapshot rather than one annual room-consumption measure. The source is the Atlanta Convention & Visitors Bureau 2024 Annual Report.
Together, these reports illustrate why a citywide event count alone is not enough for hotel planning. Philadelphia’s 21 citywides have a stated peak-night threshold, Anaheim’s room figure is a projection, and Atlanta’s future-year bookings are explicitly separated from events hosted during 2024. A planner comparing destinations should preserve those distinctions.
Denver demand over time
Denver’s convention-center series provides a multi-year view of groups, attendees, and total rooms. The convention-center group count rose from 12 groups and 76,131 total rooms in 2020 to 26 groups and 117,638 total rooms in 2021. Attendees increased from 65,500 in 2020 to 78,108 in 2021.
Demand expanded further in 2022. Denver recorded 60 convention-center groups, 311,229 total rooms, and 154,579 attendees. In 2023, the destination recorded 75 groups, 356,052 total rooms, and 208,441 attendees. The 2024 series recorded 76 groups, 415,869 total rooms, and 222,253 attendees. The 2025 series recorded 87 groups, 531,461 total rooms, and 276,536 attendees. All Denver figures in this section are from Colorado Convention Center Statistics.
| Year | Convention-center groups | Total rooms | Attendees |
|---|---|---|---|
| 2020 | 12 | 76,131 | 65,500 |
| 2021 | 26 | 117,638 | 78,108 |
| 2022 | 60 | 311,229 | 154,579 |
| 2023 | 75 | 356,052 | 208,441 |
| 2024 | 76 | 415,869 | 222,253 |
| 2025 | 87 | 531,461 | 276,536 |
The same Denver source reports a broader series covering convention and single-hotel groups. It recorded 163 total groups and 115,266 total rooms in 2020, 414 groups and 252,116 total rooms in 2021, and 843 groups and 600,213 total rooms in 2022. These totals use a wider group definition than the convention-center series, so they are useful for understanding the destination’s overall reported group pipeline but should not be substituted for convention-center demand.
Denver also reported seven meetings booked through the 2024 Colorado Convention Center expansion. Visit Denver later reported 19 future groups enabled by the expansion, with more than 200,000 anticipated room nights. Those future room nights are an anticipated booking impact, not a count of rooms already consumed. The expansion figures are from Visit Denver’s Global Meetings Industry Day 2025 report.
Booked and forecast demand
Choose Chicago’s major-convention series tracks conventions booked for future years. Its definition of a major convention is 3,000 or more peak hotel room nights, which makes the series especially relevant to large conference housing plans. The reported room totals are tied to bookings, while attendee figures are estimates for those booked conventions.
For 2024, 26 major conventions were tied to 1,158,233 total rooms, with an estimated 907,419 attendees. For 2025, 30 major conventions were tied to 1,088,787 total rooms and an estimated 798,485 attendees. For 2026, 29 major conventions were tied to 1,008,682 total rooms and an estimated 794,637 attendees.
The forward series continues with 26 major conventions tied to 1,018,595 total rooms and an estimated 772,237 attendees for 2027. For 2028, 25 major conventions were tied to 1,026,548 total rooms and an estimated 833,737 attendees. For 2029, 26 major conventions were tied to 948,513 total rooms and an estimated 765,237 attendees. These figures come from the Choose Chicago Annual Report 2024.
| Booking year | Major conventions | Total rooms tied to bookings | Estimated attendees |
|---|---|---|---|
| 2024 | 26 | 1,158,233 | 907,419 |
| 2025 | 30 | 1,088,787 | 798,485 |
| 2026 | 29 | 1,008,682 | 794,637 |
| 2027 | 26 | 1,018,595 | 772,237 |
| 2028 | 25 | 1,026,548 | 833,737 |
| 2029 | 26 | 948,513 | 765,237 |
The table is best used for planning scale and timing. It does not establish that every booked room will be occupied, and its attendee numbers are estimates. It also does not mean that the room totals are room nights unless the source labels them that way; the report’s supplied measure is total rooms tied to major-convention bookings.
Destination-level room demand
Destination-level reports add context about sales channels and future event production. ConferenceDirect accounted for 143,863 room nights in San Antonio in 2024, while Visit San Antonio’s group sales team secured 752 events during the same year. The room-night figure is attributed to ConferenceDirect, whereas the event count describes the destination organization’s group-sales results. Both figures are reported in San Antonio Moves to Fourth Spot on ConferenceDirect’s Annual Report.
Hawai’i reported 94,689 actual citywide room nights consumed in 2024. It also recorded 473,767 tentative citywide room nights generated for future years in 2024. The actual and tentative figures represent different points in the demand cycle: one describes consumed room nights, while the other describes future-year demand that remained tentative. They are reported in the HTA RFP 27-02 Global Meetings Conventions Incentives Marketing FINAL.
These examples show why destination demand should be labeled by status. San Antonio’s room-night figure is tied to a named industry source and year, Hawai’i distinguishes actual consumption from tentative future demand, and Denver’s expansion report describes anticipated room nights. For sourcing and contracting, those labels matter as much as the headline number.
Convention centers versus single hotels
Denver’s 2024 data separates convention-center groups from single-hotel groups. Convention-center groups totaled 76 groups, drew 222,253 attendees, and recorded 415,869 total rooms. Single-hotel groups totaled 913 groups, drew 157,024 attendees, and recorded 358,631 total rooms, according to Colorado Convention Center Statistics.
The two categories describe different housing patterns. Convention-center groups can require room blocks distributed across a destination because the meeting venue and sleeping rooms may be in separate properties. Single-hotel groups, by definition of the reported category, concentrate the event at one hotel. The Denver figures should therefore be used as category-specific planning signals, not as a claim that one format is universally larger.
For venue selection, the figures suggest tracking at least three separate quantities: group count, attendee count, and rooms. Denver’s convention-center category has fewer reported groups than its single-hotel category, but its recorded room total is higher. That combination is consistent with larger room-block requirements per convention-center group in this dataset, although the supplied figures do not provide a per-event distribution or average.
Occupancy and housing pressure
Hotel occupancy helps indicate how much available inventory may be under pressure when conference demand arrives. Denver’s 2024 average occupancy was 68.0% for downtown hotels, 69.1% for the city and county, and 67.7% for the metro area. The lodging occupancy figures are identified as STR/CoStar data reproduced by Visit Denver in Colorado Convention Center Statistics.
New York City reported 36.1 million hotel room nights sold in 2023, a 7% year-over-year increase, and citywide hotel occupancy averaged 81.6%. The city averaged more than 120,000 active hotel rooms in 2023, excluding rooms used for shelter or emergency purposes. These figures are from the Annual Report 2023–24, New York City Tourism + Conventions.
A single large conference can also create concentrated housing pressure even in a large market. A 60,000-person global technology conference in San Francisco used 88 hotels in its 2024 housing program. The event recorded 17,000 peak room nights and 75,000 total room nights. Maritz reported a 20% increase in booking within the block after its 2024 intervention. These are results from one event case study, not a market-wide estimate, as described in Save-the-day Sourcing and Housing Support.
For event planners, the practical distinction is between annual occupancy and event-specific peaks. A city can report an annual average occupancy while a conference faces a much tighter set of dates, neighborhoods, or participating hotels. Peak room nights, the number of hotels in a housing program, and whether rooms are actual, booked, tentative, or forecast should be recorded separately in the event brief.
