A three-day plastics conference on the Indianapolis calendar
The MAPP Benchmarking and Best Practices Conference runs September 29 through October 1, 2026 in Wabash Ballroom 1-3 at the Indiana Convention Center. The venue forecasts 650 attendees. MAPP states its mission as enabling leaders within the plastics industry to reach new levels of success. Plant managers and executives come to downtown Indianapolis for three days.
The Indiana Convention Center sits at 100 South Capitol Avenue. Downtown Indianapolis holds 7,100 hotel rooms, and 4,700 of those rooms connect to the Convention Center by skywalk. More than half of downtown’s rooms sit within blocks of the Convention Center and Lucas Oil Stadium.
The gap between the last session and the flight
Thursday, October 1 closes the conference. Indianapolis International Airport sits 15 minutes from downtown. An evening departure leaves hours between the closing session and the gate, and a room held for those hours covers them.
hotelSlots defines a day-use room as a room booked for daytime hours, typically six to eight hours. Day-use guests get the same room types and amenities as overnight guests. The platform lists day-use rooms at 103,857+ hotels across 46 states.
Four slots cover a Thursday
hotelSlots books day-use rooms in four blocks: Morning 6AM-12PM, Afternoon 12PM-6PM, Evening 6PM-12AM and Overnight 12AM-6AM. Travellers combine slots. An afternoon slot plus an evening slot holds a room from noon to midnight on the conference’s final day.
The Convention Center publishes a rule of thumb for the walkways. The facility and skywalks lock at approximately 11 p.m. and reopen at approximately 6 a.m., and the exact timing depends on the event. An attendee holding an evening slot should plan that last leg at street level.
The weekday booking window
The conference runs Tuesday September 29 through Thursday October 1, so every night booked sits midweek. Engine’s Indianapolis dataset draws on 1.2 million public rate observations between May 2024 and April 2026. September averages $117 a night there, against a $128 annual average. May is the local high at $158 around the Indianapolis 500, and February is the low at $107.
Day-use inventory books on a different clock from a nightly stay. Dayuse publishes an average day-room price of $87.43 for Indianapolis and lists day rooms at up to 75 percent below the overnight rate, with free cancellation until the last minute. Payment goes to the hotel, with no prepayment. Each hotel publishes its earliest arrival and latest departure on its own page, and those times are fixed.
hotelSlots runs a request model. The traveller submits the city and the dates, and the request goes out to hotels in that destination. The pricing page lists the service as free to use, with no commissions and no fees. Confirm the slot hours on the offer that comes back, because the property sets the arrival and departure times it will honour.
Engine measures rates from searches made 10 to 180 days before check-in. Its Indianapolis reading is that the month matters more than the lead time. A fixed conference date settles the month in advance, so a weekday day room becomes a same-week decision.
What a day room costs against a fourth night
Dayuse publishes an average day-room price of $87.43 for Indianapolis. Engine puts the Indianapolis annual average nightly rate at $128 and September at $117. The published day-room average runs about $30 below the September average and about $41 below the annual average. hotelSlots puts its own day-use band at 30 to 75 percent below the nightly rate at the same property.
Each figure comes from a separate pool. The $87.43 is a platform average across Dayuse’s Indianapolis partners. hotelSlots’ band is that platform’s published range. Engine’s $128 is a par rate, the cheapest publicly available price at the moment of a search. A fourth night adds a full overnight charge to the conference stay. A day room buys only the hours the traveller needs.
Downtown properties that list day-use rooms
The hotelSlots directory for Indianapolis lists 273 properties, presented 24 to a page. Downtown addresses across the first three pages include Aloft at 136 East Market Street, Conrad Indianapolis at 50 West Washington Street, Courtyard Indianapolis at the Capitol at 320 North Senate Avenue, Courtyard Indianapolis Downtown at 601 West Washington Street, Crowne Plaza Hotel Indianapolis Downtown at 123 West Louisiana Street, Embassy Suites by Hilton Indianapolis - Downtown at 110 West Washington Street, Fairfield by Marriott Inn & Suites Indianapolis Downtown at 501 W Washington Street, Hampton Inn Indianapolis Downtown IUPUI at 414 West Vermont Street, and Hampton Inn Indianapolis Dwtn across from Circle Centre at 105 S. Meridian Street.
Downtown Indianapolis also holds 200 restaurants within walking distance of the Convention Center, per the venue’s published figures.
Booking the final day
Match the slot to the flight. An afternoon flight calls for the Morning 6AM-12PM block. A late-evening flight calls for Afternoon 12PM-6PM, or Afternoon plus Evening for a room that holds until the airport run. The Overnight block covers an early arrival ahead of the Tuesday opening session.
Indiana does not appear on the restricted list. hotelSlots names Florida, Hawaii, Iowa and Washington as the states where travel laws restrict day-use bookings.
Confirm the slot hours on the returned offer. Compare the total against the cost of extending the conference stay by one night. A midweek conference that ends with a flight home leaves hours that a fourth night would charge in full.
