Green Valley Ranch (a high class Stations Casino) is near I-215 and Green Valley in Henderson. Sunset Station is further east in Henderson, on Sunset Road and Stephanie. Sunset has a much more local vibe to it...GVR tries to attract higher income tourists as well as locals, and isn't quite sure what it aspires to, IMHO.
If you are looking for locals casinos because you think you'll get a better deal there, don't count out South Point. Its five miles south of Mandalay Bay, and not far from the Anthem/Seven Hills/Sunridge Heights area of Henderson.
And tracking back to your last question about Bingo, Sunset Station has it (and I think has machines). GVR doesn't have Bingo at all.
