Hi Mark and Tracy,

I also think you should do all 4, as I love them all and wouldnt be able to decide which one not to visit!

I think you will be fine putting plenty into your holiday, the first time we ever went to Florida (about 10nyears ago)we had a 14 day pass, and went to Disney everyday. We didnt need another holiday afterwards, but we came home with fantastic memories and fell in love with Florida magic!
