We haven't been to Universal or IOA in probably 8 years or more. Since we now have, a son old enough to appreciate things at universal/IOA we'd like to visit. I don't know where to even begin planning for this. We have been going to Disney every year for the past 11 years. So planning for Disney is a no brainer for us. This is all new territory! A little info: Family of 5 Me, husband, DS (8), DD (6), and DD (8m) at the time of travel. Staying at a villa about 15 min. driving distance from all major theme parks Dec. 28th - Jan. 7th. We are HUGE Harry Potter nuts! Have a 5 day disney park pass (probably will use between the 2nd - 7th) That leaves the 28th - 1st for another theme park. We know that is probably the busiest time of year for any theme park. Do you have any advice to make this trip as successful as possible? What attractions are musts? Is there a FP equivilent at uni/ioa?
