I know you can...but I haven't a clue how to do so. On my most recent cruise...I had the great pleasure of having one of the same servers I had my cruise one year ago. I was very very happy. Towards the end of the cruise, I asked him (Stoyan) if we come back in a year, could we some how request him and he said....."you mean you didn't request me"? I felt bad saying no but I told him that I never knew you were able to do that. He said, "yes..you can". Silly me never asked how. I guess I just assumed it would be a piece of cake to do but now that you bring up the subject....hmmmm....I don't know!!!! lol.
