I will give only this piece of advise ....
DO YOUR HOMEWORK !!!
Posting a thread is a start but you get all this misinformation as well.
First off, I have known many men who have gone to Vegas and were busted with SPs, that includes SWs, and none of them were formally charged. They usually just take a statement from you and possibly book the SP with a misdemeanor. The LE tend to charge those that take advantage of visitors, that would be the agencies and ladies trying to turn a trick into some thing more.
Second, stick with the Indy's and if you can rent a car, rent a taxi or get a hotle lift to drop you off to go see them, most are located nearby and it really is more convenient. These SPs are quite good and numerous that you are sure to find what you want.
Third, yes it is going to cost you more ... this is VEGAS !!!
Fourth, as others have mentioned stay away from SPs who cruise the casinos, they are only trouble waiting to happen. These girls know what they are doing and will only use you as prey.
Fifth, advertising on the strip whether it be by fliers or those flatbeds that driveby every so often are RIPOFFS.
