Trip Highlights
  • Short daily drives let you actually enjoy stops

Money Savers
  1. 1Pack a cooler — grocery stores are scarce and pricey in the Keys
  2. 2Stay in Marathon or Big Pine Key to cut lodging costs
  3. 3Skip the seaplane, take the ferry to Dry Tortugas for half price
  4. 4Free sunset at Mallory Square beats $20 bar tabs
Heads Up

Book Key West lodging early — it fills up fast
