Thanks JoeyandDavid,
That answers our question perfectly. Perhaps you can help with another one.
On our last cruise (P&O) we were able to take advantage of one of their wine packages. This meant you bought a booklet of wines and essentially you got 6 bottles for the price of 5. We would look at the evening's menu before dinner and select your wine to suit what we were going to be eating that evening. You then ordered your wine via telephone and it was ready waiting at your table when you arrived. It worked very well.
As someone who is always on the lookout for a bargain I wonder if Celebrity offer similar packages?
Del.
