Sab...Good choice not to go. The Keys are an excellent place to hang out for a week or so. Your draft will somewhat determine where you can go and wheter or not you will need to do the Hawk channel or bop inside to explore. If your draft is around 5 feet or less I would suggest that to start your trip you try the Hawk channel to Key West as quickly as possible if weather permits. Then you can explore Key West and head back with the ability to duck inside if the weather gets snotty without worrying about your time line.
If your draft is closer to 6 feet...your options are more limited and I would simply go to the Rodriguez Key anchorage and then Marathon and putter around in the offshore reefs as weather permits rather than get too far from home and risk getting socked in.
Is your boat IN Miami or are you proceeding there from somewhere else. If the latter...don't miss out on Miami or Coconut Grove either!
