Key west aquarium... get off ship, walk through "mall area" take a right walk towards museum it is right there maybe a five min. walk in all.
Captian Marvins- take tender into GC., get off boat take a left walk down the street, it bends a bit, keep going, store front is yellow on the right hand side, about a 10-15 min walk
Coz mini golf- get off ship walk down cement pier (do NOT cross RED line- don't know what will happen but military men with machine guns are there and signs that say don't cross red line)
Take a left, walk until you see a piazza and fountain area turn right and two blocks up is the mini golf you need to walk up a stone stairway as it is elevated.
