That's a really tough one to answer!!
I am going to try and be objective because I do like a bit of Disney!
If you really don't like Disney at all then don't go! Whilst the skating is good its nothing out of the ordinary in my opinion and its the entire costumes, skating, scenery music etc that make it. If you are totally new to skating and its like your first show then do it as you might be blown away! However if you've been skating for a bit I wouldn't bother.
Essentially it is people dressed as the characters from some of the Disney movies, in Worlds of Enchantment they had Toy Story, Little Mermaid, Cars (which literally were cars driving around the ice!), Frozen and something else that escapes me all interlinked with mickey and Minnie and donald et al.
Hope that helps in some way! if you decide to go I do hope you enjoy it!
