When discussing our trip with my Dad, he had a question that I don't know the answer to. I know the tipping is $12/day/person as the recommended amount and that you can tip over. How does that work if you aren't going to eat in the MDR at all? (any food for that matter, since he's on a G-tube). He's wondering legitimately if the servers do anything else that he would tip them for? Obviously room attendant is another matter altogether.
