Went to Haze on a Thursday because a friend of mine had a hook-up there. There were about 15 of us total. We didn't have to pay a cover and bypassed the line. She got us a table right on the dance floor. We had to buy bottles which was fine because we were a large group. As the other reviewers mentioned, drinks are expensive (of course that is the case for just about any nightclub in Vegas) and if you can hold your own like I can, you'll be broke before you're drunk!.
The music/lighting that night was AMAZING. Wow! Everyone was super into the music and feeling great! I think there were a variety of reasons why this ended up being an amazing night - being hooked-up, no line, cool party people, and the table right next to the dance floor that was roped off and gave us a ton of room to dance.
The few times we ventured beyond the velvet ropes of our table onto the dance floor, we were shoulder to shoulder with people and there was really no room to dance. It was pretty packed and it was a total sausage fest. I see why they charge guys so much to get into Vegas clubs. They need to find some way to get hot girls there! I think if we didn't have a table and a place to sit and dance our experience would have been much different and we probably wouldn't have stayed very long.
Overall, we had an amazing time but only because of the table, the amazing music and awesome friends. So if you decide to go to Haze, be sure to get a table!
