A Day in Miami

Hi,
I am flying into Miami on the 05 in early July. We are spending the night and plan to spend the Saturday up to mid afternoon in Miami before heading to our house in Bradenton.
Can anyone advise on the best way to spend most of a day in Miami? Thinking of a bus tour and then a boat tour.
