We did this last week in MK, and not sure we would ever do it again. The list of rides provided from Disney that would be open when we bought the tickets changed sometime before the party started. 7DMT was down almost the entire time we were there and the wait never got below 30 minutes. It was also advertised as "and others" for M&G and rides, and the only characters were the two M&G in Town Hall, along with the princesses (4). It was much less crowded, but there was lines to get soda and treats of at last 5 people with only 1 person seems to take a while. There was a lady who was driving her scooter around and had like a six pack of bottles in her scooter, which i found very funny.
