You don't need a code; please call 1-800-227-2356 to book your rooms. Let them know that you will be attending Diana Despradel and Albert DiFazio's wedding. Or you could also email Pamela at sac9.op3@barcelo.com to receive a discount. However, I found that by calling the 1800 number, you get better rates.

Also, your credit card will not be charged until you arrive to the hotel.
