My son informed us that we should be recieving a free week as we have spent so much time at Sandals. He was mixed up. We have only ever been to Couples. Apparently after 70 nights at Sandals you receive a free week. We reached our 70 nights at Couples negril last November. Off to Couples Barbados in August for 2 weeks.
Any chance that Couples would consider such a great incentive? Probably not as they get so many repeat guests.
