This is one of the best attractions on the Strip! Getting a voucher from a third party is a better deal than getting tickets from their box office. (In my opinion.) I used Rush49.com and got two (2) Happy Half Hour tickets for $54.00.
We got there right at sunset, and I can honestly say that's the best time to go. The view is amazing and the photo ops will be proof.
The bartender in our pod was great. He was friendly and very timely when getting people their drinks. I was sad they didn't have the liquor for my favorite drink, but since our bartender was awesome, his recommendations were satisfying.
Vegas locals and tourist MUST go on the High Roller at least once!
