This past Tuesday I was a real victim of the system. I was in MK and went to Guest Relations for two requests, one was for The Wave at 10:00 in the morning a couple of weeks away and the other was for The Plaza for lunch that day as soon as possible.
First done was for The Wave and I was told only 9:30 and 9:45 were available. I asked for the 9:45 as that was closest to what I really wanted. Then for The Plaza, which was for 2:15, which was about an hour away.
The CM went to the printer for my confirmations and found that for The Wave my confirmation was at 9:30, not 9:45. And for the same day 2:15 insterad of The Plaza the system had booked me into LTT.
She could not change my reservation for The Wave, so I told her to cancel it completely. She did that and then looked to see what was available and lo and behold there was a 9:55, which was grabbed for me (and I have the paper to prove it).
And she was unable to do anything about the LTT instead of The Plaza, so she called over there to the podium and I was able to get seated.
At least this way I did not have to wait on hold forever.
