I brought some for the sole purpose of convenience. i was down the hall and 3 decks below any bar . I am in my sleepwear and feel like having a rum and coke to watch the ocean by. i did not feel a few personal drinks for on the balcony was out of hand. Idon't recall ever running back to my room to get a free drink. I agree totally stiffing the ship of booze sales is wrong but a few drinks? I liken it to having a couple at home before you go out to a restaurant or something. my bill at the end of the cruise was $836 give or take a dollar for a 4 day cruise they made decent money off me. even bought 3 $15 drinks in the coconut as souvenirs.
