Gotta watch the default on the PC site. It often goes back to the actual date rather than the search date. Had this happen a couple of years ago when I was booking hotels for a trip to Argentina. After making the first booking, thought I had booked next set of dates at another property but site had defaulted to the actual date I was doing the booking on, so after checking confirmation details discovered I had a res for that very night...with a 24-hour day before cancellation. Called PC res and explained what happened so agent contacted hotel and they agreed to wave the cancellation time requirement and was rebooked for proper dates.
