Tickets for residents are $170 for one person, and this gives you access to both parks "Island of Adventures" and the "Universal Studios" park. They are both right next to each other at a walking distance. The ticket is valid for one day. Prices for two or more days are not at the top of my head.
They have discounts for residents. There are blackout dates I beleive. Website will have all the info.
I am not from Orlando (iowa) I'll bet that information is available on their website however
