where to stay?

we are coming in from a cruise in FLL morning of the superbowl. The next morning, half of us are flying out of MIA and the other half FLL. We'll be staying one night. Where is a safe place we can stay to kill time, watch the superbowl and have fun? I can't decide between FLL area or MIA area. The earlier flight is in MIA so makes sense to stay there. We will have a car but don't really want to drive around... and I like to bid on Priceline or Hotwire so looking more for a specific area than hotel.

Thank you!
