The theme parks are great but really take it our of you ! Try to plan a theme park day then a day doing something more relaxing before doing a theme park again.
Practice hitting yourself in the face with a hot wet towel, you will be used to the humidity when you get there
Oh so true Melissa
If you have children try to make time for the rodeo in Kissimmee on a Friday night. They will absolutely love it. They even have some parts where the children can participate. My son was 16 when we went but it was a laugh a minute. It is not expensive either.
Also if you want to to do an airboat ride to see the alligators etc, try to make time to head south towards Miami to the Everglades because they are the best. The ones around Orlando are not a patch on the Everglades ones. The fireworks at the Disney parks in the evening are worth going back for. We are lucky because we can see them from our villa at Oarnge Lake County Club.
Lastly dont miss the shopping, shopping and shopping lol
Seriously, you will have great fun !
