We grabbed the tour in the Southern part of Duval street. We took the entire took which took about 90 minutes. The old town part was great. Lots of good information. The new town part of the tour I could do without. In that 20 minutes they stopped at 3 hotels and 1 museum. Seems more like trying to drum up business than running a tour. Anyway, we got back off were we got on and several hours later got bcak on to go the Mallory Square for sundown. First time in Key West, go on the tour. After that, you are good.
