Vegas Mar 10-12 NASCAR WKD

I am planning to head to Vegas Mar 10-16ish on spring break from school (UIowa). Bringing a pack of people with, but we haven't secured rooms yet.

1) Any 2+2ers interested in meeting up somewhere or going to the race on Sunday? We will be organizing a large tailgate, and you all are invited to come.
2) Anyone know what Vegas is like on this weekend from prior years? I would assume it will be extra busy this weekend. What's the best strategy for getting rooms and choosing rooms on especially busy weekends? OR Should I just check out allvegaspoker.com and assume a typical weekend?
3) Does the competition change at all on weekends like this, and at what level is it noticibale, if at all?

Not sure if I have any business posting this here, but this weekend looks to have some good potential for personal enjoyment and fishies flying in (or driving in with their RVs with preferred drivers flag flying) from all over for the race.
