Updated 8 September with full info
This year's Thanksgiving tournament is the Play4Kay Shootout to be held in Las Vegas, November 23-25 (Thursday through Saturday).
Everything you need is linked from that site. Here's the schedule. Basically there are four games played on each of Thursday (Thanksgiving), Friday, and Saturday. Stanford plays Kent State at 5:30pm Thursday. Win that, and they will play (probably) Gonzaga at 8pm Friday. Win that one and they will play (probably) Ohio State—yes, the very same Ohio State they played just two weeks earlier—at 8pm Saturday.
Here's the link for ticket sales. A three-day pass is about $60. One-day tickets are also available. The venue looks huge on the seating chart, so you can probably safely wait and buy the tickets on-site.
Travel Logistics
Prices for flights from SFO or SJC to LAS are crazy for this holiday weekend: $350 and up. Normal prices are half that or less. Southwest still has some "wanna getaway" $150 fares for the Thursday, but the return fares for Sunday are all at $300+.
Driving to Vegas from the Bay Area is about 550 miles, and about 8 hours, via Bakersfield (per Google maps). We are looking at leaving on Wednesday and spending a night on the road in Bakersfield or East of it, and should still come in quite a bit cheaper than flying.
