I stayed there a few years ago.
Calm beaches.
There was a bar right on the beach that kicked ass. Flo-Rida was there on a Friday night... open-air set up on the beach. They have bands there all the time.
The whole city is set-up for tourists. You'll have no trouble finding things to do. Everything is close by.
I was able to set-off mortar style fireworks right on the beach by the high-rise condo we stayed in. Bought the fireworks right up the street from where we stayed. Those things are illegal down here in Central FL. For good reason too,,, I fired one off in the sand ,,, turned to run,,, tripped and bit the dust face-first in the sand. It's not easy to get up quickly in loose sand. My nephew was only a baby as he watched me scramble to safety right before the mortar shot out. One of the first things he ever talked about in his life.... after he finally finished laughing.
You'll have a great time.
