Question on Key West hop-on hop-off

Wanted to take the hop on and up off bus in Key West. Does anybody know if you can hop on and off at your leisure or do you have to meet at a certain time? Does the bus take you around the island and you get off if you want to? Any info. on this would be appreciated. Thanks

We did this a few years ago in Key West. We rode the trolley through the entire route, then on the second time around we hopped off at things we wanted to see then hopped back on and went to the next place of interest. Worked great for us to see and spend as much time as we wanted at each location. Trolley runs about every 15 - 20 minutes.
