We saw the show last night and loved it! No special clothing required we are in Michigan and just wore sweatshirts. We won tickets from a local radio station and were able to meet Mickey & Minnie before the show, but this was a special event only for the contest winners. I'm not sure if other areana's will provide a meet and greet pre show or not.
Oh.....and if the little ones are easily frightened, there is a Halloween portion in the first half of the show that might scare some youngsters. My DS 5 was fine but the 2ish child behind us was frightened to the point that they needed to exit during that scene.
Some prices for "stuff" - Light up spinny things $22, Pop $6, Popcorn $7, Cotton Candy w/Mickey bday style hat $12, SMALL plush $15, light up crown $16
Have a great time at the show!
