I went to EDC Vegas 2015 and it felt different than before when I used to go to lots of events. I felt a little out of place being there by myself instead of with a bunch of people from the same internet message board, which is what it was when I was going to raves about 12 years ago in the early 2000's. I won't be going, but I can see how that might be fun for you.
I've been to two Sonic Blooms. They seemed pretty wild to me, but maybe that would be perfect for you. I'm into smaller, more psychedelic psytrance parties in the woods. Unify was a really good Colorado fest a couple of years ago. Camping festivals are by far, the best. Have a great time!
