This tour is really informative, but the tour guides can be really variable.
The properties are magnificent and the tour guides are very well versed in the information, but the tour can be a bit overblown with unnecessary narrative, for example:
My guide obsessed over correct spellings, and told long uninteresting anecdotes about Frank Sinatra and the filming of Hole In The Head, a movie few people have ever seen. The tour ran way way over the time we were told, and we ended up missing some of the best parts at the end because of all this excessive background info.
At the same time, you will learn a lof of the basics of Art Deco design features, so that you can then apply what you've learned to properties in Miami Beach in general
So -- just a warning -- you might get a long-winded guide -- budget extra time for this tour so that you don't miss any of it!!
