We had checked in at the front desk that last morning before we left for Epcot just to verify that everything was set. (I'm a planner and double checker.) It was an added on room only night. We were told by both our TA and the CMs when we arrived that there were no rooms left in the royal river view category and we were being moved to a preferred room. That wasn't a problem. We didn't mind. It was just a room to stay in before we flew out early the next morning.
We left Epcot because we were worried that we would get back from the Ferrytale Dessert Party late at night and not have a room available. Not something I wanted to deal with that late. Had they said that we had a room but needed to match up our magic bands like the first night's issue (or whatever the issue was), I wouldn't have worried, stayed at the parks and stopped in when we got back. But it didn't say what the issue was at all. For all I knew we were being moved to another resort.
As it was we barely made the boat for the dessert party due to a CM insisting we were wrong and didn't need to go to the TTC to get the boat (which I knew we did). Not only did she not know what she was talking about, but she was terribly loud and rude about it. Even DH who has a much higher tolerance for rudeness and attitude was shocked by our treatment. I have very rarely run into a CM that was not helpful and friendly. They almost all go way out of their way to make everything magical. This one was the antithesis of that. Maybe she was having a bad day - we all do, but she nearly ruined ours. Luckily I was able to make good choices to correct the CMs bad decisions and got us to where we needed to be with about 5 minutes to spare.
