Deej: There shouldn't be a time conflict since the two events have different organizers. Nonetheless, I would certainly choose Ferry Corsten over Pete Tong. Pete Tong is fine, but his music is more suited for car and radio settings, not live performances. Trance, in my humble opinion, beats electro phunk and House music, even if it's progressive House.
Commando: I am even more excited than you are, I am following this very closely, I promise to update you all.
This could prove to be a lovely journey in the desert.
Going there by car sounds fun, but I personally wouldn't do it.
Best,
