I stayed in Miami for attending a conference so I had limited time for side seeing. The tour gives you a good overview over Miami City and the most popular areas like "Little Havana" and the famous art district "Wynwood". The boat tour is a nice add-on to see some beautiful houses and another perspective of the city skyline, even though the boat tour guide was going on my nerves. The Everglades tour is nice to get an insight even though the loud speakers on the air boat did not work properly.
All in all, nice tour I would recommend you when you have a limited amount of time.
