Well, I'm currently on an MR to FLL... arrived past midnight, leaving at 6am. So why bother with a hotel (and really, it's only until 3am PT, and I'm usually up anyway).

But since I need to kill time, here are some FAQs for if you want to sleep at FLL. Some of these answers are specific to T3, where I'm at right now, so YMMV.

Can I stay airside?
- No... they lock down the concourses after the last flight... you'll have to spend your time landside and wait for the checkpoints to open up the next morning.

Are there good places to sleep?
- Actually, there is. A number of comfy couches in the lobby. Some wooden park benches in the retail area (behind the ticket counters). A couple flat platform benches. Plenty of floor space.

How quiet is it?
- There is janitorial staff vacuuming and polishing the floors (and chatting of course, but can we blame them?) There are also periodic LOUD security announcements.

Is there anything open at night?
- Surprisingly, there's a Dunkin' Donuts that's open all night long, and it has other things beyond donuts, such as sandwiches, bottled drinks, and snack.

Is there Internet access?
- YES! FLL has free WiFi.

Power plugs?
- Quite a number of them around, though most will require you to sit on the floor against the wall. There are a couple of cafe tables between Concourses E/F in T3 which are next to plugs.

Anything nearby?
- Not that I can tell... maybe a local can answer that, but nothing seems to be within walking distance.

Any public transportation?
- Sorry, seems like the public buses stop around midnight, and start up again around 5am.

Anything else interesting?
- Not really... I'm just happy for free WiFi u
