The booking on the Indianapolis calendar
The MAPP Benchmarking and Best Practices Conference runs September 29 to October 1, 2026 at the Indiana Convention Center. The venue publisher lists the programme in Wabash Ballroom 1-3 and forecasts 650 attendees. Plastics Business, the association's trade publication, places the conference and a secured room block at the Indianapolis Downtown Marriott, 350 W. Maryland. The two pages name different meeting addresses, so confirm the room set with the organiser. The forecast equals 9.15 percent of downtown Indianapolis's 7,100 hotel rooms, and 4,700 of those rooms connect to the Convention Center by skywalk. The host property carries 650 guest rooms and 42,000 square feet of meeting space on Visit Indy's connected-hotel list.
What the group segment spends
PwC valued the 2017 U.S. groups, meetings and events market at more than $300 billion. Hotels served $140 billion of it. Room revenue accounted for $30 billion of that hotel spend. Ancillary services accounted for the other $110 billion, across catered food and beverage, event space and equipment rental, ground transportation, audiovisual support and planning. Kalibri Labs published those figures in its U.S. Groups and Meetings special report, written by Cindy Estis Green with PwC. Ancillary spend runs at 3.67 dollars for every dollar of room revenue on those numbers. The report states its own limit. Its trend analysis covered room revenue only and did not document food and beverage or other ancillary revenue.
What the booking costs to acquire
Group acquisition cost sets the selling expense. Kalibri's three worked examples put it at 7.8 percent of group room revenue for an independent 200-room hotel at 30 percent group, 8.8 percent for a 300-room chain hotel at 35 percent group, and 16.0 percent for a 500-room branded hotel at 40 percent group. The report states an upper bound of 35 percent of room revenue per group, once housing, third-party intermediation and routine execution costs are counted. Between 40 and 60 percent of group business was intermediated at the point of sourcing in 2017.
The rate the booking carries is published. Group ADR ran $6.27 below Rack/BAR in 2017, after an $11.21 gap in 2015. Average group length of stay was 2.46 days. Booking lead time was 18.5 days. Loyalty contribution reached 35.6 percent of meeting room nights, up from 31.3 percent. Group contribution to guest-paid RevPAR was 17.9 percent in 2017.
The revenue the space has to carry
Kalibri tracked group room revenue per available square foot of meeting space. The U.S. figure rose from $0.92 in 2015 to $1.00 in 2017. The range inside that average ran from $0.19 at properties under $60 Rack/BAR to $1.98 above $300.
Group demand share by building size moved down over the same three years. Hotels with 8,000 to 15,000 square feet carried 23.9 percent of their room nights from groups, down from 25.7 percent in 2015. Hotels above 15,000 square feet carried 37.1 percent, down from 38.2 percent.
Downtown Indianapolis publishes its space on the connected-hotel list. Nine of those properties carry both a sleeping-room count and a meeting-space figure: 4,512 rooms and 552,957 square feet, or 122.5 square feet of meeting space per guest room. Kalibri's market averages run from 22.4 square feet per guest room in Phoenix to 12.6 in Houston and 11.9 in Los Angeles. Those averages cover every hotel segment in each market, and the Indianapolis figure covers convention-district full-service properties.
The 2025 read on food and beverage
CBRE Hotels Research analysed the operating statements of 2,669 full-service, resort and convention hotels, plus the monthly statements of 866 of them for January to June 2025. Food and beverage revenue per occupied room rose 3.8 percent over that window, against a 3.0 percent rise in total hotel revenue. Convention hotel banquet revenue fell 7.3 percent. Resort hotel banquet revenue rose 8.7 percent. Food revenue grew 5.2 percent in hotel venues and 4.0 percent in banquet spaces. Beverage revenue held flat in venues and fell 2.0 percent at banquets.
Two ancillary lines grew faster than the department average. Public room rental rose 9.5 percent and service charges rose 7.9 percent. CBRE describes both as historically negotiable costs for meeting and event planners, and reads the 2025 growth as stricter enforcement. Department profit margin moved from 28.7 percent to 29.1 percent.
The window the seller works in
The MAPP dates sit inside a full calendar. The venue lists 12 events from September 22 to October 15, 2026. The Do it Best Corp. Fall Market runs September 25 to 28 with a forecast 12,000 attendees. ATD Core4 and ATD OrgDev share September 29 to October 1 with MAPP.
Newmark's Indianapolis measure put year-to-date RevPAR change at minus 4.8 percent on Kalibri Labs data, against minus 0.7 percent for the Midwest and minus 1.2 percent for the top 104 U.S. markets. Mid-year pipeline counts stood at more than 1,500 rooms under construction, 3,402 in final planning and 3,220 proposed. Visit Indy lists Signia by Hilton Indianapolis at 803 rooms and 235,000 square feet of meeting space with a 50,000-square-foot ballroom, and the convention center's own news page opened reservations for February 2027.
