We've done the Sea World thing the past two years running. Probably our favorite park in Orlando. Nonetheless, it's time for a break from Sea World.
Re: Kennedy Space Center
While my wife, 11 yr. old son, and I would probably have a great time, it would be a dissservice to our 5 yr. old girl to put her through an entire day of the space center.
Our current plants are as such...
Magic Kingdom one day
Animal Kingdon one day
Universal/Islands of Adventure one day
Busch Gardens in Tampa one day
swimming at the hotel the rest of the days.
