I am hoping someone with more experience at Univeral hotels with APH rates may be able to help. We currently have 2 rooms booked for the end of July at PB hotel with the APH rate. Unfortunately, we just found out that we have to leave one day earlier than planned. I tried to modify my reservation online but it said there were no rooms available. So, I called and the reservation specialist said they could not change my reservation because I would lose the APH rate and have to pay rack rate for the whole stay which is now double in price. When I explained the situation he told me I should be able to let them know at check-in that we have to leave early and then they would refund me the last night. He told me just to make sure I physically check out at the front desk the morning we leave. Does anyone have any experience with this?
