Hmm ... all the pther posters are right ... I love our beaches.
I like Cocoa b/c of it's location to Disney *plus my gma lives there, perfect time to drop by and say hey*, but it's on the Atlantic, which means actual waves, and sometimes pretty big ones. To me, the water is clearer, and it doesn't hurt that you have Kennedy Space Center nearby *this might be a cute place to take your boys ... I'm not sure of the prices, we haven't been since it was free, and it's not free anymore*
I have been to Clearwater MANY times and the traffic to me, isn't worth it. I know with your travel times from your other thread that most of our schools in the area will be back in session, so that may help with the traffic a bit. Also, it does have really pretty beaches, but there isn't much in the way of surf since it's on the Gulf. Another poster is right about this being a good thing with two small children. My friend's family has a beach house off Anna Marie Island, and this is our favorite spot to beach on the west coast. Of course, this is a long drive *to me anyways* from Disney.
HTH
