- Wildlife Viewing: The Keys are home to unique marine life and tropical birds.
Layover Duration Guide
| Layover Length | What You Can Do |

Quick Tips for Your Layover
- Pack Smart: Keep a layover bag inside your carry-on with snacks, entertainment, a change of clothes, and toiletries for easy access.
- Stay Hydrated: Bring an empty water bottle to fill after security – staying hydrated helps manage jet lag.
- Download Offline Maps: Use Google Maps or Maps.me before landing. Airport WiFi can be unreliable, and you’ll need navigation in a new area.
- Luggage Storage: If leaving the airport with luggage, use Bounce, Stasher, or LuggageHero for $5-10/bag/day – much cheaper than airport lockers.
- Money Matters: Use a Wise or Revolut card for the best exchange rates with zero markup. Never exchange money at airport counters.
