My suggestion to your question is Rock Crusher Canyon RV Park in Crystal River, FL. The park has a lot of trees and ground cover between most sites along with FHUs and excellent cable. The sites are not paved, but most are fairly level. The Crystal River area is a lot less crowded than your typical tourist areas of Alabama, the FL panhandle, or areas south of Tampa. The area doesn't have much in the way of beaches, but it is near the coast and the seafood availability is great. It's great for kayaking, fishing, golf, and sightseeing. It's about 70 miles north of the Tampa area.
With that said, February is a busy month for most campgrounds in FL. If you're interested I'd call very soon. We'll be there for a couple of months this winter. Their website is below.
