we stayed down on the north end of Ocean Drive and just hung out.
The beach is good there, lots of restaurants, etc. It's a quick taxi
ride from where Blackbeards is.
lots of shopping one street over from Ocean Drive and on Lincoln Dr
The shops on Lincoln stay open to 10 or 11pm and the resturants
even longer. Everything in that area is very easy to walk to or
a quick taxi ride away, so no need for the expense of a rental car.
(if you got a rental car you'd just have to pay to park it anyway).
If you do want to rent a car and move around some, an everglades
swamp tour is pretty cool.
PM if you need some recomendations on where we stayed, etc.
