Change in plans..... I think we have decided to add the water park and more to our ten day tickets instead of visiting Universal/IOA. It will only add $250 for the five of us as opposed to about $500 and we have never gone to waterparks on vacation. I also think the kids will like DisneyQuest.
Would you like to "tour" the parks from your laptop/pc? Go to Universal Orlando on google maps, zoom in on the map, then select street view. Somehow the folks over at google managed to walk the google-cam through US and IOA! It's really cool! Enjoy!
