Had a groupon for 47$ to experience the evening high roller happy hour. The high roller entrance was located at the end the LinQ promenade - exchanging the groupon voucher for ticket entry was a breeze. You have the option of getting your photo professionally taken before entering the line up. Picture prints can be ordered on exit for 20$ each or 40$ for 3 prints. We were directed into a high roller cabin with 10 other people or so, where we were greeted by our own personal bartender who took care of a 30 min open bar. Drinks included -Jim bean, Jack Daniel, sky vodka, etc.. One complete turn allows you to have around 2 drinks. Our bartender was super friendly - he offered to take group pictures and offered us shots at the highest peak. Suggested tip of 20$ since it's open bar (price of 2 drinks technically).
The high roller was a great way of taking pics of the strip. I recommend the evening round at 7 pm-I would skip on the open bar extra and enjoy drinks after the ride-enjoy in style while still playing it safe with alcohol intoxication!
