Staff was nice. Shuttle was 30 minutes late picking me up. This sucked because this was during March Madness.
Don't waste your money upgrading to any higher cost packages. The oxygen dried my nostrils out so bad I has nose bleeds for the next 24 hours (no drugs I promise). I've never had a nose bleed before this. I had to have my nostril cauterized when I got home. I wrote the owner simply asking that he disclaim the fact that oxygen through nasal canulas will dry out your sinuses. He blamed it on the O3 that the casinos put out to clean the air. Sorry bud, I've been to Vegas a dozen times and that's never happened... Anyways, dry Vegas air, "O3" , and pure O2 through your nose is bound to dry you out. I was obviously too hungover to put all of this together, but you figure the medical professionals at Hangover Heaven would have mentioned this.
So the treatment helped for sure. I felt better. The hangover was alleviated for the most part.
** This is not a remedy for lack of sleep. So if you have been doing Vegas right and not sleeping, you'll still be tired. But you will certainly feel better.
Main reason for the one star is because of the shitty service recovery offered by the owner. He made excuses and passed the buck. I have no respect for that. He did offer me some shitty hangover pills, but I let him keep those. I paid $100 more for a package that offered no more benefit than the $159 standard package. And then I got to pay another $300 to have an ENT cauterize my nose.
If you go, don't fall for the scam. Just get the basic package. You could also drink less booze and drink more water, but why would you do that?
