I would echo this sentiment after our last trip to WDW last November. We were doing a split UOR/WDW trip and the UOR part was so much more relaxed and enjoyable. Between the fast passes, crowd levels for what was supposed to be a slow week, and cost, it just turned us completely off. This year we are going to UOR during the first week of December and the only WDW Park we are even contemplating for a return visit is AK because that was the park we really enjoyed last year but at $300 for two single-day tickets and a round trip Uber, I think the cost doesn’t equal the value for us.
I have to disagree with you here, at least in my experience. I don’t hate the preplanning, if anything it’s one of my favorite parts of a vacation, but the crowd levels and/or wait times (since wait times don’t always equate to crowd levels anymore with cutting labor hours) was the major turn off to us not immediately buying tickets for a return. I would eat the $300 day if I knew the crowds would be reasonable and I’d be able to ride FoP, the safari, and not be body on body with strangers. However, the combination of the crowd levels plus the exorbitant cost is what really makes the 1-2 punch for me.
