Ft Lauderdale/Wilton Manors is one of the chief gay destinations in the world right now, on par with Provincetown and Sitges.
We have miles of gorgeous beaches, including gay gay gay Sebastian Beach in FtL and clothing-optional Haulover Beach in North Miami. Most of the best resorts (almost all of which are clothing optional) are located within a five minute walk of the beach.
The center of gay nightlife is in Wilton Manors, a separate municipality that is about a mile and half inland, and is focused on Wilton Drive. It's possible to hit as many as nine different bars/nightclubs in a ten minute stroll along the Drive. These range from friendly meeting spots to dance bars to cruise/leather dives.
South Florida's not known for its culinary delights, but there's a wide assortment of places around town from Central/South American to Caribbean (mostly Cuban) to Asian (Thai and Sushi places of varying qualities) to German, French and Italian. We also have an abundance of that time-honored American institution known as The Steakhouse, ranging from moderate to absurdly expensive.
Though strictly speaking you can get around without a car, the only way to do that practically is to stay at a guesthouse/resort in Wilton Manors and walk around from there. FtL is otherwise a very spread-out city of houses. Cabs, while plentiful, are expensive and may not stop for you on the street if you try and hail them. You cannot rely on public transit: the service, such as it exists at all, is undependable and is unlikely to go where you would like.
We're in our rainy season now, which means hot, humid mornings and afternoons with a tropical downpour most every afternoon sometime between 3:00 and 6:00. Evenings are sultry; sometimes it's hotter (and more humid) at midnight than at 4:00 in the afternoon.
Pack light. You won't need much clothing, especially shoes. Florida is extremely casual and shorts and sneakers (or sandals) are welcome almost everywhere.
Depending on how long you're staying and what your interests are, day trips up to the mansions of Palm Beach or an evening exploring South Beach in Miami might be fun, especially if you take the shore road (A1A) to get there. Otherwise you can keep yourself plenty busy right here.
PM me and I'll give you the particulars on specific guest houses/resorts, bars, etc. We can meet for a drink or dinner if you'd like.
