I remember my daughter going on a few, a couple times to a big water park, to Sea World twice, to "Mud Day" at a park that had a big mud hole (the schools here are still doing that one....it's immensely popular); they have a fire truck come and hose them down before they get back on the busses.
And, of course, there was always "Senior Night" at Disney, sponsored by the public schools and Disney. The kids arrived after the Magic Kingdom closed and they stayed til morning. Of course, the place was full of "zombies" by 3 a.m. and a lot of them were asleep on benches and the grass.
Field trips had tapered off a bit when my granddaughter was in school. She was a naturally-ranked athlete while still in elementary school and middle school, so her trips were mostly to competitions.
We always tied in something educational with the trips and she did her homework and did reports, so the schools were cooperative with her absences, thank goodness.
