Suggestions for activities in Miami?

Ill be in Miami in two months from tomorrow, and I am wondering if there is anyone who can tell me more about the activities which are offered there, and perhaps recommend some of them.
I have never been there before, and I want to use those 10 days Ill have at disposal in the best possible way.

You can use that time to see some of Miamis main attractions and cultural monuments, such as Historical Museum or Southern Florida, Art Deco Historic District, Holocaust Memorial, Vizcaya Museum and gardens, Grooves Gallery, and when you get tired of this, there are Miami Metrozoo and Parrot Jungle Island with more than 500 hundred different species of plants and more than 1000 animals. Yes, something I wouldnt miss for the world is a visit to Everglades Safari Park, which was far most interesting experience for me when I was in Miami.
