We went on this club crawl twice... once in 2013 and second time in 2017. The first time was a blast, there were opening drinking game ice breakers, pitchers of beer and pizza at the beginning, everyone was mingling and having a great time.
The second time was a completely different experience. We got to the Rock Bar and waited there over two hours. Everybody was looking around confused waiting for something to happen. They say there are drink specials but pretty much everything was excluded, no shots, no vodka redbull, no fireball, no jaegermesiter (after we purchased the all you can drink) there were no games or any activities to break the awkwardness of partygoers for the hours we waited there.
Our host seemed to be off. I'm not going to say he or she so I'll say 'they'. They appeared to be either beyond exhausted or on 'something'. They were ZERO engaged, sitting on the sidelines waiting it out like a babysitter waiting to drag the kids to the next spot.
The club selection was poor. The last club was at the Hyde (Bellagio) where they would not give you tap water, instead they were asking $20 for a bottle of water. The best club was the CHATEAU which was a quick stop sadly.
Think this crawl would benefit from a new line up clubs (minus chateau) and new hosts that want to be there.
