We are going to WDW the first week of January (2-6). I would love to go to IOA for 1 day. What day would you go? M, T, W, or Th. There are 9 in our party. 2 families with 4 adults and kids aged 13, 11, 10, 7, and 2. WWOH is our biggest draw. We can get there at opening but will not have express tickets and are not staying onsite. I would love to do both parks for 2 days but having a hard time budgeting it.
