My wife and I have our own Sail Away ritual. We pop the cork of a bottle of champagne and a bottle of Asti or other, muscat grape, sparkling wine. My wife enjoys very sweet sparkling wine. Whatever she likes is fine with me. This takes place on our balcony or inside the cabin.
This is our romantic ritual and "The Official" start of our cruise. The first drink is always topped off with a kiss.
There are other rituals but I can't write about them.
BTW: Don't order the "House" champagne on NCL.
