Hayman is one of the top resorts in the world, they never discount and you have to pay for its reputation and small number of guests. Don't worry too much about the room rate, you'll spend more for dining and incidentals than the room costs. Also most of the rooms are rather basic, only the penthouses are somewhat plush, so if you are looking for a luxurious honeymoon you may want to get one of the penthouses (circa USD 2500 per night).
