Ok we haven't been to US/IOA or Sea World for at least 7 yrs. We are going to WDW July 21-August 2nd and the kids would like to go to these parks as well. We are having Pam take care of all our reservations. My question is this. Should we plan a two or three night stay at the Universal Resort (if so, which one?)? We are driving down and will have our own vehicle. We were thinking of doing these other parks first and then going over to WDW. If we stayed 2 nights that would still give us 10 nights at WDW. We aren't doing the water parks, so that will be more than enough time for the four parks. Any suggestions? Our girls will be 12 & 8.
