I was apprehensive about Nite Tours after reading all the yelp reviews, but was pleasantly surprised by the service. We signed up for a 4-club crawl. Our guides gave us an overview of what we could expect over the evening and then let us have a good time.
We started out at the Lily lounge in Bellagio. It is truly a beautiful lounge. It was surprising for such a nice spot we still had to go to the bar and get drinks. And even at that early hour most of the seating was "reserved." Moving on to The Bank it was another fantastic club, even if the bouncer is a big douche. We had plenty of time to enjoy a drink before moving on to the next spot. Keep in mind, even being part of a VIP group you will still have to wait a short amount of time to get in the club.
Our group was about 10 people. We had a nice party bus decked out in flashing lights, music, a stripper pole and drinks. While there are free drinks on the bus as indicated, it is domestic beer, the likes of Smirnoff ice and cheap champagne. The next two stops were Beacher's Madhouse and Light in Mandalay Bay.
Overall, I think it is a good way to hit up a bunch of clubs without having to walk or pay cabs. Great for groups!
