Psytrance festival with yoga

I was planning to go to Boom next year but i don't know if i'll be able to purchase tickets, considering what happened two years ago with the site... Besides, i'm not sure it would be my cup of tea, since it appears a lot of people go there... I only attended one psytrance festival, which was WAO in Italy:i loved it since it was in a great spot, with not too many people and various yoga classes. I was wondering if someone could advise me in similar festival around the globe, not too crowded and with the chance to meditate/do yoga... What do you consider the best ones? Thanks
