Did the Vancouver Canucks sell all the tickets? No. The UFC did. They have a fan club that you have to pay for, so of course they're going to give those people first crack at tickets. This was an advertised presale. I do feel bad for people who really wanted to go, but couldn't get tickets, but at the same time I know a lot of people who realized ahead of time that paying up for the UFC fan club was the best way to get tickets, and had no problem getting them.
I'm not a season ticket holder, no, but I don't see how an event that sells out 100% in 30 minutes is a 'fail'.
