Some just want it both ways; they want the assigned first seating, but then only go when the mood strikes them. This happens on Princess too, although it's not as big a problem because they have so many dining rooms. The problem is, the waiter and the tablemates will politely wait so we can all start at the same time--and then a no-show. Then they come in the next night and tell you about the dinner they had someplace else.
People, one or the other; please! And if you are going to eat at an alternative restaurant some night, have the courtesy to let your waiter know so we're not all waiting for you.
Thank you. Glad to get that off my chest.
