Certainly there are exceptions, but just as there is an emergence of tea partyers ... there is also (I think) a growing consciousness regarding thrift, value, worth .. etc. ... and "the vacation" is something to go and do nothing, or just plain relax (as opposed to being a taxi driver ... I've had a few vacations that needed a vacation to recover from the vacation).

Busch Gardens here in Tampa is another good indicator of how well things are going for tourism in Florida. It's staying pretty busy, especially now with Summer here.
But you are certainly correct about tourism in Florida as a whole. I wonder how Silver Springs is doing these days. I know Weeki Wachi Springs recently cut their admission price in half and Cypress Gardens is open only on weekends.
