Last year when we stayed at POP, we travelled with the 4 pack of single serving plastic bottles of wine (packed in our checked luggage) and the individual single shot plastic bottles of liquor. For $.99 cents each, I was able to get a variety of drinks, (even pre-mixed margaritas) which worked out just fine! Wine, beer and liquor are expensive at POP! If you purchase after your arrival, you can get a better deal at the Hess gas stations on property. That is where I pick up my beer! You can also buy the same little plastic bottles of liquor on-site at the Boardwalk but they are very expensive!
