Is this event worth driving cross country for?

Me and my partner are planning a trip to CA. He has never been to California and also never been to a rave or EDM event. I grew up in the 90’s and attended Ever rave back then from Narnia to EDC. Is thus gonna be worth it or should we make other plans? Please chime in and be honest. We want to have the best time ever! Also is this gonna sell out?
