In the shops U have to pay $40 to $50 for a T-shirt, $90 for a man's shirt (not good quality). We are champaign drinkers. On white night, they offer 20% discount on the bubbly!
Our tradition is to bring a bottle of Taittinger's and have it during the sail away. On 11/23 cruise on the Onward, they would not give me a bucket of ice and glasses at the pool bar. I gave them the bottle and the deck steward brought it to us.
