I would personally try Anna Maria Island or even Siesta Key over Clearwater any day. Clearwater is over crowded a massive PAIN to drive around. Plan to take an hour to get ANYWHERE even if its only a mile away is its busy. Very tourist trap and drunks everywhere.
I live here just outside of Tampa and go to maybe Indian Rocks, if I went to Pinellas at all. But almost always drive the AMI or Siesta Key. AMA is very old school florida style as it passed a law that no high rises and that includes hotels. So you have places like anna maria cottages or Sailfish on Holmes Beach and other. AMI has a trolley that goes up and down the island all day.
Siesta Key has tons of high rises and so forth but the beach is amazing. Sand is NEVER hot. I love Siesta Key as well, and you can find alot more rooms and so forth here. If you got Sarasota (Siesta Key) you have to try Owens Fish Camp and they have tons of non beach to do there like Ringling .
