NEED some suggestions on a place to stay in Miami.

JS - Thanks for all your help! We booked Loggerhead Marina for a launch ramp just outside Jupiter.

The Standard Spa, Miami Beach - Miami Beach Boutique Spa Hotels | Hip Hotels in Miami Beach

Nice place. Not cheap.
Decent docks, but it can get rough. Do a good job tying the boat bow out..
Welcome to Miami. $19 cheeseburgers...

You can get over by the Fontainebleau as well... All the old school hotels there.. Eden Rock, etc.

Or just do the typical and run to Miami Beach Marina, tie the boat there and hit any southbeach hotel like Clevelander... That'll put you on Southbeach. Yes, there are ATMs around. You'll need it.
Coconut Grove is quieter. Tie up at Grove Harbour.

Can't believe I forgot about Loggerhead! They are a big chain of marinas and their Palm Beach Gardens location has a big fenced lot 100 ft off Donald Ross road with a boat ramp across the ICW (Burt Winters Park, Juno Beach). Perfect spot for what you need!
