Jan, I am surprised that they are using the fancy china and crystal at Tapas on the Terrace. I would be afraid, since it is a buffet, that there would be extensive breakage. Of course, I wouldn't call a Tapas restaurant "gourmet" so I may be confused on which is the fourth restaurant mentioned in the press release.
I think we would probably enjoy Oceania; it is just that I hate paying for more than the lowest level of cabin and I think we would need a Penthouse on Oceania (balcony, space, and refrigerator are musts). We are going on Celebrity Century this year and have a concierge class cabin which is exactly same size as concierge class on Oceania and the amenities are almost identical. This will give us a good idea on whether Concierge or Penthouse is minimum cabin for us on Oceania.
As for the water or cokes, we go through at least a dozen a day. It would be terrible having to find them let alone have to pay for them.
