We did okay. Hitting a Grand Jackpot on the first night helped.
We used the certificate to book a cruise on the Ascent in April leaving out of Barcelona for 9 nights. Concierge comp stateroom.
We also received a cruise certificate on our 12/10 - 12/17 Ascent cruise. On the bottom of the certificate in small print it states it must be redeemed within 30 days of the issuing cruise end date.
