We got to the hotel and our plans had changed. 15 minutes later, we decided we weren't going to stay. The hotel wouldn't cancel our reservation for us without charging us for a half day, even though we had spent less than 5 minutes upstairs and hadn't touched a single thing in the room.
It's not like the hotel wasn't nice, but the lack of human understanding and customer service was disturbing. It's unfortunate that any sort of one time gesture couldn't have been made.
With all the options out there, I will certainly not be staying at a Hilton again in the future.
