It looks like you had an awesome time 🙌
At the time when I tried to solve it, I didn't get further than DRONKFEST, and I might have been accidentally motivating myself to get myself some more beers.
I'm trying to figure out what it might be... Let me guess, it's nothing to do with beer?
We surely had! Thank you.
Hmm, you want a hint? ^^
