I always like to throw in the reminder that there really is no such thing as a "Private Table" other than those booth things in Enchanted Garden in the same way you would find them in a land-based restaurant. Sure they might be separated, but there may be less than a foot between them in some cases - especially because the dining rooms were built around the shared table set-up that used to be the standard for cruises. There is only so much space in which they can put the tables, so the more people demand their own private table, the less space there gets to be in between them. More than once we've had a party at the table next to ours try to start up conversation without even raising their voice.
