Burning Man is amazing, and I recommend that everyone go at least once. But if you didn't get tickets, there's much to be seen elsewhere in the world--perhaps this is the year to try something new? For example, here's a few festivals I would like to attend:
Symbiosis, Camp Tipsy, Porcfest, Boom, Envision, Tribal Gathering, AfrikaBurn, DragonCon, Loi Krathong, Ghent Festival of Light, Frozen Dead Guy Days, Bosch Parade, Ephemerisle etc.
There's a bunch of other festivals listed here:
