We just returned from our cruise two weeks ago and I know how you feel. I'm cheap too when it comes to paying the liquor bill. We packed 3 bottles of wine and one bottle of scotch in our luggage (the luggage you give to the porter). We had no problem at all and I was glad we did it. I even brought a glass of wine with me from my cabin each night for dinner and nobody questioned me. I say go for it!!!
