From the HangoverHeaven.com
website, based in Las Vegas:
We continuously make loops up and down the Las Vegas Strip. Most of the
larger casinos have a “Tour Bus” pick up area, that’s where you’ll want
to crawl and wait for us to pick you up. All of the casinos have this
area pretty well marked–if your eyes are too blurry to read signs, ask
the concierge or just some person walking by. We have faith in you.
Below is a
list of casinos
with Tour Bus pick up areas and those where
we can pick you up at the main entrance.
Once on the bus, our physician will take a brief medical history, and
assess your hangover severity score. Then, numbing medicine is applied
to your skin and a small IV will then be placed. Most people find it
completely painless. Then you start receiving the treatment."
