We're first-time visitors going in October, but plan to spend some "non-park" days. Here's what we have planned: Discovery Cove (arguably a park, but it gets us into Sea World and Aquatica later. Sounds like great down time between busy theme parks.), Kennedy Space Center (DH's father worked as an engineer from Mercury through Apollo 11), Tampa for the aquarium, considering going north to swim with manatees. Also planning on visiting the Singing Tower gardens. Probably will see an evening show at Capones. There's also the huge ferris wheel in an area that also has Madame Toussad's and a skeleton museum and a few other things.
