fergus - just wait till you see what your room stewards does for you before deciding ahead of time you won't tip. The tip is totally up to you and you can have it removed from your sail 'n sign card - there is no issue there. And then it will be up to you who and amount you want to tip. But, when you see what your cabin stewards does you will "want" to tip believe me . . . . just wait and see, you'll love everything and feel an overwhelming need to tip - maybe even more than suggested. Same goes for your waiter . . . .
