Traditionally I've been taking the family to Disney World for about a week around Christmas time for the past few years, but I'm strongly considering going to IOA/UO/SW this time around. I've been to all three parks in the past as a kid...around 12 years ago, and had a decent enough time. I understand both companies mad significant changes to the park. My question is, is there enough to do to keep us occupied for 4 or 5 days between the 3 parks?
