You need to go to a travel agent for this. No one here can give you quotes for a cruise on any cruise line.
In the Crystal brochure, a room on the highest floor is deck 11 and costs from $7300 to $15,780 per person. There aren't many places that will discount a Crystal cruise by much, so plan on paying close to those prices. I would get on this quickly because the sailing date is close. Crystal is one line that doesn't reduce their fares as the sailing date gets closer. They're not a mass market line and therefore their fares generally stay the same. The prices do not include airfare but they do include port taxes.
