If you are in Florida now and looking for something to do, the seafood festival is coming up February 15 and 16. You can find info when you Google it. They get about 25,000 people in the 10 block town of Cortez. That is near Bradenton (gulf coast). Last year admission was $3.
I have never been there but heard it was a fun place to visit. I'm going with 6 girlfriends and staying in a hotel (YUCK- I hate hotels). Going by RV I'm not sure where to stay, but would think you would need a car to drive to the festival.
