We just went Jan. 31-Feb 2 and there was no wait on rides. The longest we waited was for Shrek about 30 minutes. Everything else was just about a walk on. So due to the time that we go in Jan. we will stay at Disney and make a day hopper trip to both IOA & US for just one day. We were able to do both in one day this time but went back the next due to staying at their hotel and had tickets for 7 days. We have been now 12 times and US/IOA has not changed very much and certain times of the year, we can do both parks in one day and ride ALL.
