I'd been on one duck tour before (Austin, TX) but this was a lot more like a comedy show and almost more of a tour of the Hollywood stars homes on the various exclusive islands than a tour of South Beach, but the important thing is that you absolutely get the fun, party vibe of Miami. Our guide Richie and our driver (Captain) Willie were great. We did see a lot of Miami art deco (not as impressive as I thought it would be although the neon at night may make the architecture more distinctive), learned a lot of Miami history, saw a lot of fancy boats and mansions, took pictures of Biscayne Bay, and enjoyed people watching on Ocean Drive as we cruised down the street in a bouncing, amphibious duck boat. All in 90 minutes. Definitely worthwhile.
