I'm planning a family RV trip during summer 2007. We fly from South Africa and land in Atlanta, GA. We're planning to take the kids to Disneyworld in Orlando and then do a southern road trip to California. Is this feasible in 5 weeks? My then girlfriend (now wife!) and I last did Route 66 from Chicago to the Grand Canyon and back in 3 weeks, 14 years ago in a 10 year old Dodge Charger!
