Key West, Florida is beautiful. You will get more bang for your buck if you rent an electric car. We rented a six seat electric car and had my son sit in the middle of the middle seats. We drove all over Key West. We saw the Hogs Breath Pub, Southern Most Point, shopping, beach, USS Mohawk and Coast Guard memorials and toured everywhere allowed. There are places you cannot go with the electric car due to safety reasons but that was fine. I would strongly recommend renting the electric car for $126 for 4 hours +/- for 7 people. This equals roughly $18 per person to see a lot more than the Trolley or Train. A word of advice: look around before you purchase souvenirs because there is two shops that have everything for $5 -- sweatshirts, t-shirts, pants, shorts. A woman on the boat bought the same sweatshirt for $43 dollars that I paid $5.
