Expensive short circuit. Very hot day in Key West, we decided to book trolley tickets - wow so expensive compared to other hop-on hop-off but as we didn’t wish to drive we decided to do it. Frequency i8s only every 30mins (and it finishes very early too) so, if you just miss one you have a long wait. The route is very short so no idea why it’s so costly. Some of the drivers were amusing and welcoming, others had clearly gotten up that morning in a bad mood! Would I use it again, no.
