DH's father has decided he'd like to do a large family vacation. After bouncing around many destinations Disney was suggested.

However my idea of doing Disney and theirs are a bit different. They are talking about staying at universals hard rock and also doing the universal parks. I've only been to universal once many moons ago. While I'd like to do the universal parks this trip in addition to Disney it still seems like we get more perks and convenience staying on Disney property.

So am I wrong, right or just blinded by Disney?

Oh and I've already tried suggesting staying at both resorts but FIL is convinced it will be a hassle to move mid vacation.
