I would go for memorabilia, as some others have said - attraction posters, framed maps etc. Do you know what they're into? Pins, characters, films, attractions? If you have any idea on their likes and dislikes then a $500 piece of Disney Gallery art would be an amazing gift.

One of my first thoughts. Would have loved to tie it in with a night at the Grand Cal, but word has it that they wouldn't be spending much time in the room. Seems they really want the rooms, so we may be going that route.

My fears on memorabilia are 1) getting them something they don't want (I have found that people can be picky about their memorabilia), and 2) getting them something they already have, or 3) they don't have any place to put said memorabilia.

I have personally been on a "no more crap in my house" kick lately, so that may be clouding my judgment.

Hmm, how much DOES it cost to get an outhouse set up?

Actual construction is cheap, but the association fines are steep.
