Hi! Pulled the kids (7 & 9) out of school last May 5-9th. We found the crowds to be very manageable - especially that Monday at MK. We rode everything we wanted more than once and never waited more than 5-10 minutes except for Splash and Jungle Cruise.
It was a week of record high temps, however - mid 90's the whole time! We're used to heat, though, and it wasn't too bad.
Would I take them out of school again? Probably in elementary school. Both did fine on make-up work and teachers were happy for them. I think we'll go in 2005 the day school gets out - like May 27th.
Have fun, fun, fun!!!
