Well, there's always my office...
Seriously, one small piece of advice - the 87th and I-435 hotels tend to be popular with girls, but I think less so with customers. Although there are usually a number of providers there (in fact, the hobby may be their main source of revenue), and as one provider told me, "the management doesn't care and the police don't mess with us here," I think those hotels tend to make guys nervous for some of the other types of crime that can happen there.
The Residence Inn type places also tend to be popular; there's a fairly nice one just off 435 at Holmes.
