CG, of course they do. i used to live and work in vegas and vegas is unique to many cities.
everything overcharges there! lol!
when it comes to escorting, our business is 95% (ok, i made that up, but its close) new. its not local repeat friends... so there is really no longer connection or whatnot. its so transient. tourist money. gambling money. etc, etc.. people save up all year to go to vegas and blow it on anything and everything. $500 hands of blackjack, $500 steak dinners, $500/night hotel rooms and $500/hr escorts.
my rates are real similar no matter where my wanderlust spirit has me.. 300/hr, 280 if youd like to return. i like when people return. if they return more and more then it can even go down to 250. i dont increase when i go back to vegas, but i certainly understand why many do.
