I made my reservation for 2 nights on the web, using the APH code. When I called to extend by one night that night was showing available for the APH rate. The operator said the only way to extend the reservation was to cancel it, credit me the 1 night deposit, then open a new reservation and take a new 1 night deposit. I asked him to verify the rate before canceling, and he found that he couldn't book the APH for all 3 nights. He told me to go to the web and reserve the room as a single night, but to be advised that I may be asked to switch rooms after the second night. His only suggestion for avoiding the move was to rebook at the higher rate for all three nights.
So, long story short, I have 1 reservation for 2 nights, with 1 night paid, and 1 reservation for 1 night, with 1 night paid. Does it make sense to try and call to have the two reservations combined? I'm not concerned with getting any of my deposits back (the hotel would end up getting the money anyway), but I would love to avoid switching rooms/
