Everything was as advertised: got into every club without a cover charge or much of a wait, and got as many free drinks as we could drink on the bus between clubs. The hostess (Julia) and her bartending helper were both awesome, helpful, and a lot of fun on the bus. Every club we went to was an absolute blast as well.
We only paid $40/person for the VIP Nightclub tour due to vouchers we found online, and it was a great deal for that price (the clubs themselves were charging about $40/person cover). If you do buy a voucher online, MAKE SURE TO CALL ROCKSTAR TO REDEEM IT prior to showing up. Unfortunately one group didn't do that and thus couldn't go on the tour that night.
If my review were limited to the night of the tour, it would be 5 stars for sure. I dock a star since it was extremely hard to get in contact with Rockstar to redeem our vouchers. In the weeks leading up to our tour I called probably a half dozen times to reserve our spots and left a voicemail each time (plus emailed), and never received a response. It took probably my 7th call to finally reach a human to book our slot.
