I'm not sure if it's changed this was my first time going in 2018 and I had a great time with my family
I never went in 2013 so i dont know.
I went years ago when I was little and from what I can tell is it's pretty much the same.. however I havent been in eons sooo I'm sure they've added a few things here and there, some rides etc (there was one I hadn't remembered from before). I know some rules have changed but none the less I'm sure you and the family will enjoy ur time!
Wikipedia has a good synopsis of the year to year changes.
