Celestial Strings Prize

Hello!
My husband and I just got off the Horizon and we saw the Celestial Strings show (our favorite production yet, the performers were absolutely god tier), and we always like to go early, get good seats, grab a drink and enjoy the pre-show antics they like to do.
We were sitting and I was approached with a pen and a little paper and asked to put my name and room number down. She did it with a few more people and they chose a paper, placed it into a glass jar and a person was approached with a scroll and an employee told them to meet them in the atrium afterwards and that’s all they needed to know.

Well the woman that won has been on dozens of cruises and said she’s won before and she knows what it is but didn’t say so I am so awfully curious if anybody knows what you win?
I believe I heard someone say a bottle of champagne or you get to meet the performers.

I am just absolutely so curious! Thank you!
