first trip to WDW I was entirely unprepared, it was Thanksgiving Week and I had done no research at all. My traveling companion had been once almost 20 years before & had grown up at DL. I think we waited 2 hours for Soarin, 90 minutes for ToT... fast pass line as it broke down as we were waiting. That Soarin line was just the dullest space, I don't think I have waited stand by there again.
Overall, my wait times at WDW have always been better than my trips to the theme parks here at home. Last trip we ended up waiting 40 minutes at Splash & actually really enjoyed the experience as I got to see things in line we normally miss. After years of being commando tourists we have slowed down and have learned to just enjoy the experience, whether its a walk on or a long wait.
