I don't have any set movies, but this year I decided I'm watching as many Disney movies that I haven't seen, or have only seen once and barely remember as I possibly can. So far I've watched Cars, Tinker Bell, and a Tinker Bell sequel whose title I can't remember for the first time, and I watched Lilo and Stitch which I've only seen once, and The Many Adventures of Winnie the Pooh which I haven't seen since I was little.
Surprisingly my DH is getting in on the action too. This year we'll definitely be able to recognize a lot of characters that we hadn't on our first two trips.
