We have a trip scheduled for December 18-29 this year. I'm planning on getting 10 day passes. I figured the first week we would really try to get all of our touring in, and the second week we would use our passes to pop into the park for as long as we could deal with the crowds and then tour the resorts. We'll be staying at Fort Wilderness in a travel trailer, so we'll have our own little home to relax in. We've been to WDW four times, but never during the holidays. For those of you who have more experience, do you think this is doable/enjoyable?
