My husband and I will be going to Universal on Thursday, June 12 of this summer, and we'd like to hit the highlights of both Universal Studios and Islands of Adventure all in that one day. We're planning to get there before the parks open and have our tickets in advance. We're not staying onsite at Universal, and since the Express passes will be at their most expensive, this option really isn't in our budget. Which park is usually better for the afternoon/evening? Is there a difference, or will the waits be basically the same at each park? We plan on doing all of the main thrill rides.
