One Wednesday, One Night
The Indiana IT Symposium runs Wednesday 14 October 2026 at the Indiana Convention Center, 100 South Capitol Ave, Indianapolis, IN 46225. The venue assigns Sagamore Ballroom 4-5 and forecasts 300 attendees. SIM Indianapolis hosts the event. EFM Events is the organiser of record.
The published shape is one day. A delegate who arrives Wednesday morning and leaves Thursday morning buys one room night. The group is 300 rooms on a midweek night.
300 Room Nights Against 4,700 Connected Rooms
The venue footer carries the downtown supply on every page it serves. Downtown Indianapolis holds 7,100 hotel rooms, and 4,700 of them connect to the Convention Center by skywalk. The symposium's 300 forecast attendees equal 6.4 percent of the connected rooms and 4.2 percent of the downtown rooms.
Every skywalk-connected property competes for a share of that pool. The pool closes after one night.
Three Events Share the Building on 14 October
The venue's October 2026 calendar puts three events in the building that day. The Best Practices Expo and Conference carries 1,200 forecast attendees across 13-15 October. The Metal Treating Institute's Furnaces North America carries 1,500 across 12-15 October. The Indiana IT Symposium carries 300 on the day itself. The three forecasts total 3,000, which is 42.3 percent of the downtown room count.
Tuesday 13 October carries the Economic Club of Indiana Luncheon at 300 in the 500 Ballroom, Furnaces North America's second day and the Best Practices Expo's opening day. That night carries the heaviest forecast of the three around the symposium. Thursday 15 October opens the Midwest Multifamily Conference at 950.
The Rate Frame on the Desk
Downtown Indianapolis hotels averaged $209.11 in daily rate and $135.20 in RevPAR, per the Downtown Indy Alliance snapshot citing CoStar and STR data that Bradford Allen published on 19 March 2026. The same snapshot gives 64.7 percent downtown occupancy against a stated U.S. average of 62.4 percent.
Engine measures the city on a par-rate basis. Its Indianapolis page puts the average nightly rate at $128 across 1.2 million public rate observations between May 2024 and April 2026. October averages $134. Engine defines a par rate as the cheapest public price at the time of each search, and its page states that negotiated corporate rates sit below what it shows.
Three Hundred Rooms at the Two Published Rates
300 room nights at the downtown average of $209.11 reach $62,733. The same 300 rooms at Engine's October par rate of $134 reach $40,200. Both numbers are ceilings. They assume every forecast attendee buys one downtown room night at that rate, and no source states that assumption.
Neither figure belongs to a property. The venue publishes supply and no rate. The organiser publishes no rate. No hotel rate for the symposium night appears in any source on this event, so the desk prices the night against city averages or against its own history.
The Departure Window
The venue publishes a rule of thumb for the building and its skywalks: lock-down at approximately 11:00 p.m. and re-opening at approximately 6:00 a.m. A guest on the Wednesday night departs inside that window the next morning.
The event page lists "Doors Open: Check event website". The organiser's site publishes no start time, no end time and no session grid. The front desk has no arrival clock and no release time to plan a housekeeping or breakfast window against.
No Published Block to Quote
The organiser publishes no housing page, no room block, no block rate and no cut-off date. Its site is one page, and /hotel, /hotels, /travel, /agenda and /schedule all return 404. A front office that takes a call about a symposium rate has no official block to match and no published deadline to quote.
Supply is published. More than 1,500 downtown rooms sat under construction at mid-2026, with another 3,402 in final planning and 3,220 proposed, per the same Bradford Allen report. Signia by Hilton Indianapolis adds 803 rooms in a 38-storey building beside a 143,500-square-foot Convention Center expansion, with a December 2026 target.
The group arrives once. Price the Wednesday night against the 300-room pool and the three events sharing the building. Hold the Thursday release until the skywalks reopen at approximately 6:00 a.m.
