Actually, the other way to enter USF is through the Hard Rock Cafe entrance/exit. You need to get your hand stamped at IOA and then head over to USF. Instead of going through the main entrance, you walk around the Hard Rock Cafe and enter through the entrance near Nick Studios. The line at the main gate can get very long. The HRC entrance is usually very quiet. You can also save a few steps in walking to some attactions. I knew one employee who read a romance novel there and she finishes one every few days!
