I like the Gulf beaches better, myself. Clearwater, Sanibel, Anna Maria, Siesta Key, etc. It'll be a bit longer of a drive, but IMO, worth it. White sand that stays cool underfoot (and is very soft), lovely water with fewer waves, awesome sunsets.
If you head out east to the Atlantic beaches, just head out the Beachline (SR 528, toll road) and you'll hit Cocoa Beach.
