Martin was very informative about the architectural styles in South Beach, as well as delivering a short history of the area, those that developed the area and the people that ultimately created the area one sees today. He also provided tidbits of movies that had been filmed here and who the current owners are in some instances. The tour was about 90 minutes, mostly outside, though we did go into two hotel lobbies. The walking is casual, with stops along the way where you are standing and listening to information about a particular building. As such, the tour is doable for most people. We returned a few hours after this tour to take the "Neon Tour" which we do NOT recommend. The presentation was almost exactly the same as what we had just heard on the architectural tour. While the guide was knowledgeable, it was still repetitive. Very little about neon was learned. Moreover, the tour started way too early. It started before dark and even at the end of the tour the lights were just beginning to come on. Sort of takes away from the point of the whole thing.
