Wow! The same thing happened to me although my party was not cancelled but was rescheduled. I did the same thing in preparation for the party. I stayed in contact, had a letter confirming the date and time and the day before, when I called to triple confirm I was told that I had the time wrong, even though I had a letter from them confirming the time. We were able to reschedule for later in the day and they did give me a substantial discount. It was a couple of years ago so I don't remember how much the discount was so although I was not happy, the party went on. Nice to know that this is what they do when a bigger name calls. I thought it was a one time occurrence. I will definitely let anyone I refer to them know about this tendency of theirs. But the girls had a fabulous time once we were there.
Pros: Really cute, girls had a great time, all the parents have to do is watch - or participate
Cons: Made my reservation MONTHS in advance and still got rescheduled
