I'm headed to vegas again this march. But I first tried these water beds last year/April. It was the most inexpensive, non invasive, BEST massage I've ever had. I spent 20-30 minutes in the machine and I couldn't hardly walk when I was done [I'm not kidding]. If I lived in vegas, id have one of these every week. It was the best money I'd spent while out there.
You take off your shoes
you lie on a table and put your head in the headrest and the girl hits a button
Note: you should probably have realized by now that you need to head to the bathroom before doing this-and don't do it after you've just eaten :D These water jets are no joke. From the tips of your toes to the top of your head, the jets get everywhere and then some.
Enjoy!
