If you are looking for the 45 minute flavor KP gals are very YMMV. Pic's and looks? I have been there many times and have yet to see a gal I was not physically attracted to. I would also say pics are fake, but they are a fair rep of what she will look like. My KP rule of thumb is... if a nice rack matters to you=always subtract 1 cup size from the website's description of the gal.
On the 60 minute ticket you will get KP's version of GFE which isn't the same as a true GFE. The gal may allow all the things a GFE would include but it will most likely seem extremely mechanical. Most KP gals have their routine, you just happen to be there too. lol
If your just looking to get the job done the 45 minute is usually all that is needed.
If your looking to spend some extra money the 60 minute will do. So far i have only had one experience with KP that I would have considered a REAL GFE, I was only there for a 45 minute visit that time too.
If it matters to you at all that the encounter feels GFE you might consider spending a little bit more than the 60 minute rate at KP and see a TRUE GFE
