I usually stick with the Lido Ice tea with lemon and sweetner. At dinner, I enjoy a nice glass of wine and maybe a Kaulah (sp?) coffee & cream after dinner. Sometimes if we go to a lounge to listen to the music, I will order the fru fru drink of the day.
We've never brought any liquor on board. For the little we drink, it's just as easy to buy it on the ship.
My hubby drinks the soda during the day and will indulge in the some nice wine in the evenings.
