Try Clearwater beach it's beautiful and a bit further down "Johns Pass" near Maderia beach also moocha good nd cheap jet skiing .
Enjoy your hol!
Keep going south on the west coast, St Pete Beach, Pass-A-Grille, Fort Myers, Venice (great for finding sharks teeth) Bonita Springs, Captiva & Sanibel Islands are all fabulous and some completely unspoilt and almost deserted.
