We took the motorhome and camped at the Disney campground. It was nice for the kids to be able to kick back in familiar surroundings. They were 3 and 5. We'll be going back when they are 8 and 10 (real soon now).
The quick serve meal plan, we thought, was a good price for what you got in quantity/quality. We did have a lot of tickets left over, but that was only due to our inexperience in how they work.
Debating if we are going to take the 5th wheel down the next trip or fly and stay in motel.
There's a big difference in price if you go in the off-season (they list the dates when to go). Seems like TDay, Xmas and Feb were the big "off-season" times. We went in Feb. Weather was perfect and the crowds were not bad.
We booked everything direct through Disney's site.
