Visit the Miami Art Museum or the Fairchild Tropical Botanical Garden. There is a wide range of things to do in Miami.
Even better, Hotels.com will set you up with a deal on a place to stay and save you big bucks if you travel now.
One of our favorite hotels is the Beacon Hotel in the heart of South Beach. Hang on the beach all day and then treat yourself to some decadence at night. Have a good trip!
