Definitely the most wrinky-dink operation I've ever seen. We signed up for the Party Bus package and were on a party bus for all of 10 minutes. When we showed up, they didn't have enough wrist bands and said "Oh, you guys are extra." Not sure what the hell that means. But our club hopping was pretty ridiculous -- we spent 2 hours and 20 minutes at Haze, spent 10 minutes on a party bus, and then went to the Chateau at Paris. At 2:45 AM they were supposed to bring us to Pure, but I bailed by that point. Vegas never sleeps, but getting shuffled around at 2:45 AM is moronic.
Oh, and if you call them and suggest paying a lesser price than Groupon, the company will agree to avoid Groupon's fees.
Spend your $50 elsewhere. These companies are hit or miss either way. We had 9 people on the bus and would've been better off putting our money towards bottle service.
