I travel to Naples every winter, not a gay life scene town. Beautiful beaches, there is one gay bar and restaurant called Bambusa and nothing else so far that I know. But you can do a lot of activites , I like fishing so spend a lot of hours doing that lol.
Have only mostly driven past Naples though went twice to meet for lunch and twice stayed at the Ritz for biz. One time the beach was loaded with horseshoe crabs and always I think, but especially in season (probably march/apr) you have to do the stingray shuffle. They won't intentionally hurt you. Stingrays can actually be pretty friendly but you don't wanna step on one, especially not on their tail where they've barbs. So if you've got reports of them, and that area is known for it--they were there when I was there--shuffle your feet if walking in water to scoot them out of your way.
Haven't been in a while. I recall daytime stuff to do (there's a real nice downtown) but that the town and area closes up early at night. A pretty but sleepy little town.
