From what I understand, Kyle's only a fan of the Disney Parks - and even with those just the ones in the US. He'll only be interested in the other Disney Parks when a daddy sends him enough money for the airfare and hospitality.
JoJo's only a fan of becoming famous and trying to hang out with celebrities. Think back to that time last year at the Disneyland Jungle Cruise Movie premier, he was trying so hard to get attention from John Stamos and he was getting so annoyed.
At least there's lots of trainwreck potential on this cruise! It sounds like they have a big group of DCP friends staying together, so just a matter of time before they get sick of each other's bs!
