I have had the good fortune to live in some very good hobby towns, Cities like Atlanta and Dallas where there are literally hundreds of hotties at $300 hr or less, with more girls entering the business every day at a pace that you could see a different one every single day of your life and never have to repeat if you didn't want to.
Even with all this amazing talent right here at home, I still find myself taking trip after trip mainly guided by my dick. Most people would think I am crazy, and most likely they are right, but I wouldn't trade lives with any of the losers who think my life is a bit "excessive"
One suggestion I might make if you are going to make a several day road trip out of this, unless you can afford to have non stop female company, unlikely by your statement "I don't have an unlimited budget" you might want to plan some other activities on your little road trip, whether it be golf, site seeing, gambling if you are in someplace with casinos or what ever else you like to do besides fucking.
Even better of course is to find a wing man to go with you. It's not all about fucking smoking hot women, it's also about being able to tell someone, "did you see the hot chick I just fucked?" I've done a lot of trips, some of them alone, some of them with several friends, and a whole bunch of trips with just one friend who gets it and who can do his own thing while I am otherwise occupied.
