I took my 2 daughters aged 2 and 3 to see this last year. At the time they were vaguely aware of princesses and liked watching Disney's Sleeping Beauty and Cinderella, but didn't know much about the other ones.
From the first minute they were absolutely entranced. Tinkerbell opens the show and you could hear the gasp from around the arena as hundreds of little girls (and a few parents!) saw their favourite fairy.
The show was spectacular, with scenes from Beauty and the Beast, Mulan, the Little Mermaid - complete with an amazing Under the Sea 1st half finale, Sleeping Beauty , Cinderella, Snow White and Aladdin.
There were a few parts that could be called scary if your child is of a nervous disposition, such as the dragon from sleeping beauty - but they only last a few minutes.
Be warned that most little girls go dressed up as their favourite princess, the day I went it was like a Snow White convention!
The skaters were fabulous and the whole production was as slick and polished as you would expect from Disney.
The toys and plastic wands that they sell during the show cost a fortune, so either avoid the toy stalls or buy something in advance to avoid the emotional blackmail from your child.
After seeing this show my girls are now princess mad and my house looks like a disney outlet shop!
Overall a fantastic show, and one that I would happily go to see again if it comes back to my area.
