What part of Florida is best to visit during the summer?

.....any where along the Emeral Coast of Northwest Florida from Panama City to Pensacola.

I would recommend that you either go to Miami, Key West or Clearwater. Both Key West and Clearwater have very nice beaches are beautiful places to visit. I would not recommend going to Orlando as it can be very busy as many people go for a holiday and the parks are extremely busy. If you go to Orlando and go to the theme parks, you are wasting your money as you will constantly be hot and you ill have to wait in hours of queses to go on rides while you are scorching hot. Miami isn't that kid friendly but can have some nice beaches. Personally I would go to Key West for a nice relaxing holiday!

Siesta Key. I love that place.

The whole state is too hot and humid in Summer...it's the worst state to visit. The best of the worst would probably be Key West because of the prevailing winds, keeping the temperature and humidity level low.

Key West is not as gay as Floridians contend. Another key to checkout is Sugarloaf Key:

well pensacola beach has white beaches unlike most beaches on the atlantic. there are more than 50 beaches and there is one for every person. to avoid the crowd i recommend chicken bone beach. (name doesn't have to do with anything) they have like a 10 mile road that you can ride your bike on or walk with no cars on it and it is paved. however, the keys are a good place. but not key west, i have heard there are a lot of homosexual activity there.

Key West.

Orlando and surrounding area.

Fort Walton Beach is a very friendly community with beach front!
