Thanks GIna. Good to "see" you again!
I edited my question because your generous response made me realize it was a terribly ambiguous question--I am looking for ideas and recommendations, but specifically meant "where can I find threads". Bad me!!
We have done Gatorland; still laugh that we tricked the kids, who were little then, into eating the gator nuggets (we said they were--really dried out--chicken nuggets). Afterwards they were really proud of themselves that they'd done it, but wouldn't have if they'd known!!
Haven't done an airboat, but I should look into that. Dh thinks he might like to go back to the Tampa area for a beach; he didn't like Cocoa, where he killed time while I did my astronaut training at KSC.
Have you been to Busch? We loved the animal displays mixed in with the fun at Seaworld, so Busch sounds like it might appeal also.
