So when you invite a provider to take a trip with you what should you expect to pay for?  Her time? Travel expenses? Souvenirs for lil joey and gram gram?

sk a TOP Performer  she will prolly say  around $10,000+,If your me ...it would embarrass guys & gals ( took two 8 rated for $ 600 each.)Go on lots of trips for much less.If you have a lady you have seen quite a few times and depending on many variables ..ask her what she thinks.But as stated below , hope you have had overnight or such before you ask.
What you experience in the bedroom vs the actual person ... many of the top performers seem sweet ,intelligent & genuine , but having spent many many hours with a lot of them ...perception is NOT reality in most cases.
The best hope is that your both reasonable adults ,establish an itinerary,what your willing to pay ,what your not willing to pay for.
good luck

I would not recommend an extended trip with her.  You should be familiar enough with her to establish the expense set-up ahead of time.  Proceed with caution.

You would pay for time and expenses just as if it was a dinner date. The gifts for family members maybe not ... That's her choice. If you want to go shopping and buy her a few things then pay for those things. But if she chooses or asks to go shopping then she can pay for that stuff with her money she earns for her time. In otherwords you pay for time, food, hotel, entertainment, etc. Anything she wants to buy above and beyond one souvenir she can spend her own money ... Some will even give extra money as spending money so they aren't pulling out the visa at every store.
