Well, there will definitely be plenty of people there on tuesday night still. Thing is, though, you're in vegas and there is ALWAYS something to do. Last year I ended up staying 3 extra days just for the fuck of it and it was great.
Thanks for the reply. I changed my reservations/ plane to go through Wed (still have a 9-5 to go to show up to on Thursday)... I've been wanting to take my occasional foray into online poker offline, anyway.
