I hope it isn't too early to ask a question about the WCC tourney???

Could some knowledgeable member outline how a "newbie" going to LV for tourney gets tickets?

Not interested in 3/5 thru 3/10, just the Semis and Championship. If individual tickets are not available
for only those two dates, is it reasonable to show up at the Area and try to buy tickets outside before the game?

Understand there may be a premium for the tickets but....just hoping. Hoping for some experienced advice. Thanks
