Hi there,
Access is easier if you leave via the front of the Beach Club Hotel, simply walk 100 ft to the large walkway that faces the Boardwalk over the water and turn left, it is then straight on for 800 yards to the international gateway( on the way the walkway has some dips in the path which could require someone in a chair to want a push)
From the BCV, Leave the BCV heading towards the main building and take the first path on the left before you reach the main building.
The path goes on for 50 yards to a T junction turn left, and walk along the side on the rooms which leads to a little black metal gate which in turn takes you on a path very near to peoples rooms.
Follow this which does snake left and right but brings you out via a little black gate after 150 yards, turn left and only a couple of hundred yards to the international gateway entrance.
This sounds as clear as mud but do it and you will never forget it.
