I have been to WDW and DL
you can't really say which one is better you can just say the positive things
DL is the original, the onyl that Walt truly walked in and that makes it special, it's smaller but with more rides, its almost crazy! the castle is small but they have Matterhorn and Indiana Jones and DCA(I love that park!) Soarin' over California is seriously one of the best rides ever!
WDW is bigger and there are 459784967590650679560 more times to do there!
I like them both!
as of right now I'm missing DL like a mother!!
