My family and I will be driving to Orlando at the end of the month from Dec 31-Jan 8. My wife and many of her family members are participating in either the Disneyworld Marathon or 1/2 Marathon. We will be driving from Iowa to Orlando with a 3 yr old boy and a 5 yr old girl. We will have a DVD player, snacks, books, toys, tranquilizers, etc. for the kids in the car, I'm more curious about things to see or avoid while in the Orlando area-geared specifically for that age group. My wife would also like to spend a night somewhere near the beach on the way down. So I'm also looking for a kid-friendly, safe place to spend part of a day and night, probably on the coast somewhere between Jacksonville and Orlando. Thanks in advance
