This tour is very much worth doing but please be aware that it is a very long tour to be standing in one position for 3 hours without a break. The guides were friendly and well informed, however when half the group was tired and wanted to "return to base" so to speak, they only allowed half the group to do so. As one of those who were boldly told that we could not return, I was highly annoyed and my party did not tip our guide.
Overall, yes it's worth doing, just be prepared to be standing in the same position for at least 3 hours, which can be painful.
Fun and informative - thanks for the great introduction to Miami Beach!
Great fun, more an excuse to play on a Segway for a couple of hours than real detailed tour, but we did explore a lot and our guide was pretty knowledgable.
