We spent 3 nights at the Galleon last week. Very nice facility: clean, friendly helpful staff, constant security over dock area, nice pool (except water temp was hot), nice showers and bathrooms. Not cheap, but not bad considering you are in Key West and close to Duval Street and all the activities.
A big plus are the floating docks - no worry about spring lines, etc. You have a finger dock on either side of your boat.
