I have been happy to discover Miami (even if it has a very limited interest and is very touristic [more than Orlando!]) and the tour was very well organized. The Art Deco District is very nice but the time there is a bit short to see everything. South beach (where the Art Deco District is) is not interesting (it is a big nightclub). The star houses boat tour is quite nice (but they try to much to sell stuff on this boat, it is a bit boring at some point) but it is only the occasion to see nice houses and Miami arbour more closely nothing else (you will not learn much). The airboat tour on the Everglades is very disappointing compared with the one proposed on the Manatee tour. We left early (06:50 am) and came back late (11:30 pm) so do not plan anything else. Overall it is the tour I liked less during my stay (because I was disappointed by Miami Beach, but the tour itself is well done) but still it was a pretty nice day and the guide and the driver were very kind and funny.
It was an awesome tour!
Manatees are so cute and very well protected. It is necessary to be very patient as it can take a long time to see a few. But seeing one is a great experience. The Airboat tour was really excellent (ride and environment). Excellent day!
