Is this available on the Dream, I have looked all over the Cruise line site and can't find anything more than where you can order it under gifts. I am also certain that I saw something about it the other day, but not now. Can anyone give me any info or point me in the direction of the info I swear I saw? Also I know the cost of the beer mug, but what are the cost of the 16 oz beers? And are the mugs glass or plastic? Also do these have to be purchased ahead of time or can they be purchased on ship?
