It was nice. Didn't have time to do every thing we wanted to but no complaints.
I highly recommend
www.tourguidemike.com for planning your days somewhat. The site will also let you know the best days to visit which parks.
If you don't care about seeing the fireworks and light shows at night, that is a great time to knock out some rides. As well as EARLY in the morning. Oh, and don't use the extra morning hours at the parks. EVERYONE goes to those parks on those days. Don't do what everyone else does.
