We have only one day to be at Universal. There are 6 of us going, all adults with one who is not big into rides, but has fun watching the rest of us (that's my mom)
IOA was my favourite, certainly has the best "big" rides with Hulk and Dueling Dragons. Plus Spider-Man might be the best attraction at any theme park.
Studios has a bit more variety though if it isnt just for thrills
Go to universalorlando.com and look at the attractions at each park. Decide which park has more that you will enjoy.
I would personally leave toward US because I think it has a better mix of shows and different types of rides. Also, I'm not a water ride person, so that leaves out Dudley Do Right, the Bilge Barges and Jurassic Park at IOA.
I agree also.We can blow thru IOA in 1/2 A day.But US has more to offer in my opinion.
This might change when HP opens tho.
You can do both in oneday,but its gonna be A long day and you won't see it all.
Islands of Adventure, hands down. The rides are more dynamic and diverse, the way the park is setup allows you to accomplish everything without zig zagging and the theming itself is breathtaking.
Oh, and there's that ride there, what is it called...Spider Man!
