I watched Frozen last night (finally) and I really enjoyed it, far more than I thought I would (from the trailers I thought Olaf would be irritating but instead he was hilarious).
The DVD also had a Mickey Mouse short called ‘Get a Horse!’ which is just delightful. You can watch it on Youtube here (embedding is disabled) and it’s just great. At first I thought it was genuinely an old Mickey cartoon but then, well, I’ll let you watch it.
