Most all are. There are a couple of “premium” restaurants that aren’t, but the additional cost isn’t that much more.Are all your meals and snacks included in the fare price?
It gets really confusing, which is why I’m glad my wife takes care of all this. The various drinks charges (from bottled water and pop right up to all the varieties of booze) can change considerably, depending on whether you bought a drinks package, which one you bought, or if you paid for a more “inclusive” package overall, or if you have some kind of status with the cruise line. It boggles my mind, but MrsT keeps it all straight.
