Great post as you were able to get this ball rolling without having a total flame out...
My experience is that the newer/younger ladies are entering the market at the 600/hr rate. While the established ladies are in the 300-500/hr range. What I have seen is that the price break for multi hour appointments seems to be diminishing. I truly enjoy longer, even overnight experiences, and they used to come with a hefty break in the $/hr. Now I see many ladies not giving a break until after 4 hours and at 4 hours requiring a meal. I have, in the past, had many engagements that were 8-12 hours for 1800-2k. Now that rate seems to be about 2400 as a starting point and many at the 32-3500 range (some significantly higher). I am finding that price range a bit out of my 'comfort" zone, so I am setting several shorter engagments at the 2hr for 700 range than one for an overnight.
I believe that TER is part of a double sided coin as a hobbiest can research more, and see more. If the "newer" group of ladies can get the 600/hr and not give discounts for multiple hours MORE POWER TO THEM. I find that I am having just as much "fun" with the ladies in the 26-32 range and their prices seem to be more agreeable.
This is all a YMMV situation. If I had unlimited funds, I know of 3 ladies right off the top of my head that I would contact ASAP. But alas, I am obviously not in the demographic that they are marketing too. It is all about fun and comfort for all involved. Other than NCNS, or unnecessary drama, I try to keep it all in perspective. It is a hobby for me, I do this for fun, but I realize that for every one of me, there are probably 4-6 D-bags that double book or lead a lady or two on (i have actually done this by mistake once, and know the wrath).
To all I say... Keep is fun, beware of BS, and be happy happy happy.... IMHO $.02 worth
