My hubby and I will be in Key West for 5 days, staying at the Almond Tree Inn in late March. We plan to spend one day doing an all-day snorkeling/kayaking trip and maybe another day going to Dry Tortugas. Was wondering if we should rent a scooter for 3 days or is that overkill? Any recommendations on stuff we should see/do while renting our scooters? Thanks!
