Try them all.
You are an unique individual, and you can't get a true feel for any given place till you try for yourself.
Just because one person says Oh you definitely need to check out Moonlight best girls in Nevada. Or go to Mustang its an experience of a life time. Does not mean you will view any of these places the same way.
Just because someone says girl X at house Y is the best does not necessarily mean she will be the best match for you.
I would just start with the one closest to you and go from there.
Keep in mind when you eventually get down to Vegas. The closest legal brothel is at least an hour away from Vegas.
As for price depends on which girl you are talking to and what you are asking for.
The dollars will usually go further in the smaller brothels, but you will need to allow for travel time
I would definitely drive yourself to each house if you are able to do so. It will be more cost effective for you in the long run.
Good luck set your budget for each individual visit and stick to it. Start with the one closest to where you are based and go from there. Also if you and one lady don't click well don't assume the ranch is bad. Odds are high that there will be at least one or 2 ladies in each individual brothel that you will like and match up well with.
Oh very important make sure your feet don't stink. Nothing worse than the smelly feet tax! Other than maybe the bad breath tax. So wash your feet and pack a lot of breath mints.
