So kind of a personal question so please do not judge, is the party just a big drinking fest, or is it something that a non-drinker will be comfortable at? I only ask because I have been at IT conferences with a after hours party that just turns into a frat party with a bunch of drunks, which I personally do not find appling.

I’ve only been to it in 2022 and it didn’t feel like that. Nelly was playing and most people were dancing.

I don’t drink myself and last year did not feel like a frat party at all. Just good times networking

It's like a normal mini concert, you can go the drinking route and drink as much as you please or just go network enjoy the music and food. Their should also be shuttles going back and forth if you want to head out early. If you don't want to head back with the drunk crowd would recommend heading out a little earlier to avoid the pileup.

Last year was the worst because of the sphere traffic from U2 and the formula 1 construction

I don’t drink and the party’s were good fun. Some people go to the extreme and drink plenty! Massive queues for food though! As @suitemike said, last year traffic was horrendous. Plus one guy on the coach threw up so getting off to walk was a welcome change!

When I've been, which is many times, it's not a drink fest. You should be fine and have lots of fun
