It used to be that we could change/cancel our reservations within 1 day of the stay. It's gone up to 3 days on most reservations, which is tough when you have to adjust your plans while on the road (happens quite a lot in my line of work). It can be assumed that lots of folks who stay 75+ nights per year need more flexibility around their bookings. Perhaps one of the perks of platinum could be the option to change/cancel reservations within 24 hours of the stay. Even better would be the option to pay the advance rate but still have the option to change/cancel the reservation within 1 day - that's perhaps asking a lot, but maybe we could have just a few per year?
