And if turned down at guest services instead of having a fit, try going back again and maybe a different employee will accommodate your request. An example--- (this was on a different cruise line) we received a voucher for a bottle of wine, and it said it was from our TA. Now I knew it was not from our TA because it was a cruise line offer and our TA only gives OBC because he knows that that allows his customers to spend it any way they want. I also had called prior to the cruise and was told we could turn it in for an equivalent amount of OBC. When I asked for this onboard, I was turned down the first time. The second time, I was asked who I had spoken with, and honestly could not answer. I was then told that she would have to check on this with headquarters. A day or two later, we received a call that the OBC was going to be given to us to replace the wine voucher. And, BTW, I cited that representative is one of the crew who made my cruise special.
