Go to
http://www.oasisresort.com/ for the basic info on the oasis.
The oasis open poker tournament happens twice a year, I always go and it's a cool place to be, good tourneys, lots of poker including O-8, good people etc. Rooms $15 a night for players in those tournaments,
http://www.oasisresort.com/index.php?PID=CASINO has a link to the poker room and oasis open info. The oasis open is run by Jan Fisher and Linda Johnson, so obviously it's run very well.
I recommend the place when you want to get out of vegas for a few days.
