It can be more enjoyable than the front of Epcot. There isnt an opening show like MK, so there really isnt anything you miss other than the crowds. There have been days when we were in Epcot and through WS before the front entrance was even opened (if the CMs would open the gate about 10 minutes early which doesnt always happen, but its great when they do). We would then wait for a short time (never more than 5 minutes) near the split for Soarin' and TT. Once the main entrance was open we would be off. We have been on the very first ride of Soarin' entering this way. Got off and right back on again in fact before making our way to TT all in less than an hour.
