Very good tour, 5 stars. I've been on hundreds of coach tours throughout the world. Almost 700 days on cruise ships. So, I rate this outfit as tops.
I really like the narrative and personality of their drivers, plus the speaker systems inside the trolleys worked, loud and clear. We ran into two of their guides. A couple of years ago, down at Ft. Lauderdale, Princess Cruises had us on an expensive coach tour of the rich and famous areas with a tour guide who was terrible. No one could hear his blatting.
There was one glitch. At the station we bought our tickets at and where we were to originate, the first two trolleys were loaded. We were getting frustrated but the girl from the booth came over to us twice to apologize and assure us the next would have room for us. There was another couple waiting too. They talked about going over and getting their money back wondering why they didn't warn us things were overbooked for that day to start with. But in short order our concerns were rendered moot.
We book them next time in Key West for sure.
