We love to go to HOB and grab drinks (just about every night) to be honest. I don't know what time it closes in December, but maybe you could check their website. Sometimes though when they have live entertainment, if it is a more popular band or artist, the cover can be a little pricy so that would be something to check out in advance. Also, the kiosk was open past 12am in May when we were there (but PI was still kickin' too.) They had what I like to call "Hidden Whiskeys" because I bought two and swore the bartender forgot the whiskey until I stood up from the park bench only to realize I was quite tipsy. I also love POFQ indoor bar, but if I recall correctly it closes around 12pm or shortly after. Good luck finding some place to enjoy your drinks. We drive so we buy lots of beer, wine and liquor to mix drinks aside from buying drafts and specialties in the parks and while dining which helps us curb some of the costs as well.
