My husband & I had the Royal Suite Cabin # 1558 on the Radiance of the Sea, an RCCL ship but the sister company of Celebrity. We were hosting a group and had evening coctails in the suite. All the liquor was included (also champagne & beer) and mixers. The Suite is located close to the concierge club, in the evening the butler would bring trays of appetizers, for the entire group. The chocklet covered strawberrys were wonderful with the champagne.
We had a butler, who was very accessable and did see to all our needs.
It's a great way to cruise, wish we could do it more frequently!
