In my experience, travelling ladies add variety, but many don't scope out the market and so overcharge, etc. We get a lot of transient providers on their way up the I-35 corridor, flying in from Dallas on their way on a tour, etc.
There's also a fairly elite group of travelling ladies that service corporate entities, but those women are usually booked before they hit ground. That's a market to tap into if you find connects.
Lastly, the local providers vary in quality, but the market is fairly saturated IMHO, mostly if you don't have an in, or just hit the right time, the main question folks will ask is "what do you do that I can't get here already, from someone comparable, for the same or lower price..."
I'm always sort of smiley at the travelling ladies that sort of blow in with... IM THE BEST EVER.. COME SPEND 400 AN HOUR BECAUSE IM AWESOME.
Really? Better than Kat, or Gemma, or Kaci, or.... any of the great locals.
Meh... thought I'd chime in...although it is funny you asked if you take local girls' money when you travel... of course you do, the pot of play money isn't just labeled "travel only" ...
