Some while back I had a reservation at a Hilton near SNA and because of a mechanical issue the inbound flight missed the SNA curfew so we landed at LAX and had buses to SNA. I didn’t check in until around 5am. When I arrived there was no problem. After reading FT, I learned that the room could have been resold as a no-show and my entire 5-night stay cancelled. Now if there is any chance of being late I call the hotel directly and “confirm” my reservation and arrival time, just in case.
