I do not know the answer to your question.
But, I am on the same sailing as you and we need just 3 more people to sign up for a free meet and mingle party....can I ask you to visit cruisecritic.com - go to the RCCL board and hit the link for meet & mingle. Read the info over and if you would to meet 23 other great people during your cruise just sign up!!

Thanks,
Ted
