I work with kids and eagerly await their reports after a Disney trip - I find that a common description for the kindergarten set, when describing the entire trip, is “It was SO COOL!!! I rode on an airplane and swam in a big pool that had a slide!” Not much else compares to a plane and a pool at that age, apparently.
My personal tip as a parent of a wild toddler - always save the “let it all out and relax” activities for last in the daily schedule. Kids are used to the idea that they need to “keep it together” for various parts of the day - school, soccer practice, homework, etc. But then when they reach whatever point is a signal to them that they get to be “done for the day” and just chill out / rest - they really want to be done after that. They don’t want to switch back “on” (and I think that while the parks are a ton of fun, managing that level of hyper stimulation without melting down is in some sense “work” for a young child.) I say let the relax and unwind time come last and maybe be a longer event, but after everything else you want to do is done. Small kids are almost always much fresher in the mornings anyways and kinda burned out by the afternoon.
