We are going to Florida Disney in Christmas. Anyone could give some suggestions about renting car(should we rent one??), hotel, good places to visit......
If you are staying in Orlando at all time you don't need to rent a car. Most hotels provide free shuttle service to all major theme parks, and chances are you'll be inside one theme park per day so you really don't have the time to drive around. Orlando is small and boring, not much to see anyway. You would need a car if you want to go to other places in Florida like Daytona, West Palm Beach or the Keys.
There is kind of Disney Package, staying in Disney resort, my friends all like that, cheaper and easier for people just want to visit Disney World. Check with travle agency, they would have more information.
