Tina - No drinks are included, be it alcoholic or non, including bottled water. Obviously shore excrusions, gratuities, wine, etc are not included. On the positive side, they have open seating, with 4 different restaurants, small ship environment, and personal service. If you are in a PH or above, you also have a Butler. You can bring whatever you want to drink onboard for your cabin, and you can take wine into the dining room, although there is a corkage fee.

We very much enjoyed our Oceania caribbean cruise a couple of years ago and would do O again and will with the right itinerary and right time of year.

I think you would be pleasantly surprised. IMHO.
