Well...it wouldn't be a trip to Vegas without being so hungover that going to basement of MGM for an IV sounds like a good idea. For record- I'm writing this on behalf of my hungover honey. He got the $100 package and said it was well worth. An anesthesiologist was the one who placed an IV, so you know it's legit. The only thing worse than being hungover? Being hungover on the day you fly home. This was a life saver for him.
*I like the suggestion some one else made in their Yelp review of pre-hydrating. * worth a try to avoid the hangover? Why not!
