Google usasexguide Vegas for a relatively high traffic review board for all of our favorite degeneracies.
MassageFinder is also kind of unique to some states where you can find some really smoking hot semi-legits ($$$$ tho)
Anything near the strip is going to be the worst places to go, value and quality. If you are absolutely stuck with that as your only option and you just really wanna say you got it tugged in Vegas, dont go in with high hopes and you might find a gem.
Enjoy the higher % of korean girls there, thats the big difference I see.
