I've had some great dates, TS and GG both. Some longer dinner dates, and some high end GG multiple hour dates. I tip, pretty consistently, or at least I think so, in an effort to show my appreciation when a date goes really well, or I just like her a lot.
Here's what I think. Except for some kind of special fantasy, which, I don't have much experience with, but which they won't usually do anyway, (two words, baby oil) you are better off just sticking to the 1 hour program and cross your fingers, and be prepared to tip if things go well.
Dinner dates, not that fun, she gets bored, you have to order a salad or some shit, or, even worse, expensive appetizers she does not want to take more then a bite or two out of.
Don't think girls like it that much, think they like the cash, but just not that much extra fun or attention later to justify, IMO. I don't know why, could be me, they want to get back to the room to take calls, don't know.
Bottom line, my best dates have not been the ones I paid the most cash for, consistently, I think girls look at you differently when you start flashing, or talking, big bucks
