First of all, we did not stay on property. We were in the park by 9:00 and went first to Jimmy Neutron, planning to get a express pass for Shrek afterwards. Got to the express pass line at 9:20 and the return time was 4:45! Also, we returned another day at around 11:00 and there were NO express passes to be had. My advice is to either do Shrek first or get an express pass first thing. Hope this helps.
