Easy, just following these steps:
1. Bring one or two empty large suitcase when boarding.
2. Order lots of Redbull cans and don't open them, order at least 10 a day and pack them into suitcase for consumption at home..
3. Order the most expensive beer (probably an IPA) several times in different bars and don't open them, pack them as well to your suitcases for bringing home and drink later..
4. Order several shots of Chivas or some other Whisky straight up, no ice or water (I prefer Gentlemen Jack) and pur them into an empty water bottle. Bring home for future consumption...
5. Drink so much that you crash into bed every night (and the sunbeds on deck for a nap every time before lunch)
I have faith in you! I really think that by following these easy steps that you will get the most out of your drink package 😀
