All you have to do is go to the International Gateway, which is between France and England, go straight down the path along the canal. You can either catch a boat from the boat dock there and get off at the Beach Club/Yacht Club (dock with lighthouse), or you can follow the path straight ahead and walk. Maybe 5 to 10 minutes. (when it splits don't take the path to the left, that's the Boardwalk)
First you get to the Beach Club, keep going until you get to the pool area, and head back toward the building. Beaches and Cream is between the two resorts. If you get to the entrance to the Yacht Club, you're too far.
