Quote from nanoplasmDifferent organizer for the two events.
Cascade for Vegas, and CFB for Oakland.
OKC = Oklahoma City, which is Legion Events.
Quote from Darth_Solo_I had VIP in Vegas and it was worth it. I'm getting VIP for OKC just because of how well it was done in Vegas.
I'd encourage you to keep an eye on the Legion web site; I've heard that they're going to be doing some different things for VIP come OKC. (last I heard, something I'm working on right now is related to one of the new[ish] benefits)
