Different from Bushnell. Hmmm.
I really like the Crystal River area, but that's almost the same thing in the same place.
Gulf Coast beaches? Either Pensacola to Panama City, or barrier islands north of St Pete.
SW Florida, for warmth, Sarasota to Naples.
Atlantic Coast beaches: Jax, St Augustine, Flagler, Daytona, Cocoa, or if you want to be warmer, Palm Beach down to Miami. Choices can be small town or big city along the coast.
The Keys are certainly different from where you are now.
If you like your winter climate but seek more urban life, developed attractions, mixing with crowds, then Orlando is right in the middle of things.
All of these regions/locations have RV parks to fit most preferences and budgets, though costs go up as you go south, get urban, or approach water. If you want beach, getting right on the beach can be expensive, since most beaches can be developed for a higher return with permanent housing.
