Last-minute: AAA codes beat corporate codes — wider room/car availability and less restrictive blackout dates.
Call the hotel directly for last-minute bookings — front desk can sometimes beat online rates.
For last-minute rentals, neighborhood Enterprise locations are cheaper and have more availability than airport.
HotelTonight app sometimes beats corporate codes for same-day bookings — compare before committing.

Best corporate code for last-minute bookings?

AAA codes (00017500 for Hilton, AAA rate for Marriott/IHG) — they have fewer blackout dates than corporate codes like IBM or 3M.

Are last-minute hotel rates always more expensive?

Not always. Hotels with low occupancy drop rates 24-48 hours before. Apps like HotelTonight surface these deals.

Can I use a corporate code for same-day booking?

Yes. AAA, AARP, and most public codes work for same-day bookings. Company-specific codes (IBM, 3M) may require advance booking.

Best last-minute rental strategy?

Check Enterprise neighborhood locations first (cheapest), then Hertz airport (most inventory). AAA CDP works on both.
