What's the best way to reserve & pay for a hotel rm you only need for you know what?
Some girls do incall from rooms, motels, or hoods that affect my comfort zone.
I don't mind getting a smoke-free, clean hotel in a nicer area, but want to avoid putting it on my card.
How do providers pay for rooms..?

Maybe get a prepaid CC?

You are willing to pay for the room but dont want the room on your cc nor do you need the room for more than an hr or two, so why not ask the lady if she wouldn't mind getting the room in her name and you reimburse her the cost of the room?

That way after you finish, you can be on your merry way and she now has an option of staying in the room and enjoying the hotel ammenties or even possibly seeing someone else sometime later in the day.

If you do this, stick with a well reviewed and trusted provider, you dont want to meet in a hotel parking lot, hand over money and watch her drive off.

*also only give hotel money if you are meeting at the hotel, you can settle the rest of the bill once you are in the room together*.

I have done Naomi's advice with a regular of mine.
Will try it with the new girl if she is reliable.  So far she has been professional in communications.
