We've had the experience on certain trips where all the parks were really packed but then we hit the sweet spot and suddenly one of the parks was deserted. I was reading on one of the crowd calendars for example that today was packed at DHS and deserted in MK. We pretty much commit to one park and stay there for a while, but I'm starting to think that's a mistake. Does anyone ever go into a park and see that it's really busy and try a different one?
