While I certainly understand tipping a room steward as if there were 2 people in a room (when in fact there is only you), should a lone traveler also tip the waiter and asst. waiter double, even though you are one diner? I would think not, especially if you are seated at a full table of other solos. Any tipping suggestions for people traveling solo would be greatly appreciated.
I tip for one person dining as each person at the table tips. However I tip more for cabin service as the cabin needs to be cleaned whether occupied by one or two. I usually give the "extra" early in the cruise and find I always get great service.
