Luvjabad,
The Mariner's Negril Beach Club is a separate company from the Negril Beach Club Condos. If you read Sparky's post above, note the name of the resort and the phone number. His reservation was listed under NBCC, but if you check the phone number, it is NOT the NBCC but the Mariner's Negril Beach Club.
The booking company in Sparky's reservation has the resort name wrong. This can happen as it did in his case. These booking companies are there as a convenience, they do not usually have any first hand knowledge of the resorts. They are order takers. If you would, could you please provide the phone number of the resort in your booking as Sparky did? This may clear everything up for you as well as everyone else.
