In the afternoon we wanted to hit another resort, and went to the Krystal, a 5-7 minute walk from the ship, which welcomes both cruisers and crew for free day use, no towels included (bring ship towels). Dont go the long way out to the main drag, take the shortcut down the back street. Ill give these directions because there are so many messages asking how, and it is a bit hard to locate. Go off the gangway, walk to the right around the circular building, then across the square in front of the flea market, then head for the large white wall with a yellow wall behind it, go through the gate at the left end of the white wall, and go down this street to the end, where you will see the Welcome cruisers to the Krystal resort. You can see this route from an upper deck on the dock side of the ship.
This is from the cruise critic board which I printed and took with us, but before I could even read my directions about locating the colored walls, my DH was already out the fence and down the side street. You may think you are going the wrong way, but keep following that street and when you come to the end to the left you will see the small gate welcoming cruisers.
