I have finally talked my husband into a day at US/IOA during our WDW visit in early August. I know it is difficult to do both parks, even one, in a single day, but that is our time frame. We are both in our fifties and will not be doing any of the large coasters. It is our first visit to the Orlando area. I have been reading here and found the information very helpful. My question is if we bought the one day, two park pass AND the booklet of express passes for Universal only, would that be feasible? There are only two rides in IOA that are musts on our list, Spiderman and Jurassic Park. We would like to ride all or most of the headliners in US. I thought we could be at the park before opening, purchase our tickets as early as possible and then hot foot it over to IOA and ride the two rides we are interested in there. We would then use our express pass booklet to finish in US. Do you think we could see most of what we wanted with this plan or do you have a better idea?
