Use extreme caution in Vegas.
The only time I have been totally ripped off was in Vegas.
Read about 'clip joints'.
I was hammered late at night (how all bad stories start...) and left a strip club. Asked cab driver to take me to an ATM. He took me to ATM at a 'massage parlor'.
Girl at desk was hot as shit. I decided to stay there and have a massage. They charged me a decent house fee, then off to the massage.
In the room (more like a booth) a hot chick literally rubbed some lotion on my hand while she wore gloves. She rubbed my hands for about 10 minutes and told me that if I purchased a bottle of champagne we could go to a VIP room for better service.
I was out of cash, and was not going to run my ATM card again... my spidey-sense was tingling. I said sorry, that's it and I left.
I got in another cab and in chatting with the cabbie he laughed and told me I got caught up in a 'clip joint'.
They view the tourists as sheep and 'clip' them. The place was packed with lots of other drunk horny dudes ready to keep paying for upgrades in search of a release that would never come.
Stay away from MPs in Vegas. Also stay away from the girls that cruise the casinos. See only well-reviewed girls that are on TER/P411.
Alternatively travel outside the city to the legal brothels in Nevada.
Everything is 'organized' in Vegas and if you are looking for incall service go to the brothels outside the city. otherwise stick to outcall
