I just saw this post over at the Orlando Attractions blog and it reminded me (once again) of what a great field trip opportunity the Disney parks are. EPCOT is probably the most educational of the Disney parks; but we manage to find educational opportunities in all 4 parks. We always count our days at Disney as school days too.
We're hoping to have this school year complete before our trip to FL in May - but we'll still count our time at Disney as field trips. :) You've gotta love a place where you can learn and have fun at the same time!
