I, actually, really like National Treasure 2. Despite this, I don’t think Disney will ever make an attraction based on the movies. A scavenger hunt based upon in it Liberty Square would be pretty cool, though.
What's funny is I always catch National Treasure 2 either at the beginning or the end on cable (I saw it in the theater though). It was a lot more ridiculous than the first one, although both were good. Unfortunately an attraction is unlikely
