Yeah I feel ya for sure, It's kind of a wemf tradition to do it this way so I suppose that's why they do it. This year they did reveal the venue early which is out now (same location as last year). As for the lineups, I understand that it's tough to be committed to buying a ticket when you don't know who's going to be going, but if you're a fan of the genre and listen to enough electronic music than you'll be happy regardless. At least that's how I look at it.
Yeah i'll be there all three days for sure, wemfs my home away from home aha. The little things are all for the most part taken care of. Cars are parked really close to the camping area so a quick 2 minute walk to lock shit in your car/get shit out. We grabbed locks for our tents as well which isnt totally necessary, people are generally pretty nice and respectful there but its still a good idea. Wemf provides things like a charging station where you can go and they have a bunch of phone chargers for you to use and charge your battery up. theyve got Water stations to get nice and hydrated for partying, i believe theres going to be free wifi and showers provided too.
I'd say if you're really worried about the whole lineup thing, than wait for the first set of artists to be announced and if you're satisfied with what you see at that point, nab a tick!
