Sienna got us in and I guess that is what it is all about. Our host knew what he was doing and we had no experience in Vegas so did not know the rules. We had to tip him separately so he could tip the bouncers, but I did think we would get in quicker, and also not have to wait on our own outside Vanity. If you are doing what all the other party groups are doing you will be fine, but if you want something specific I think they struggle as we had to fend for ourselves at Vanity, even though we had paid for Concierge service.
Like I said we got in and maybe this is how things are but just a shock to us as we are not used to spending that much money.
If you know what you want and are happy with the rules, I recommend this group as they were efficient, know what they were talking about and did the job.
Next time I may try myself to get into the clubs and then I can get a better picture in my head of what these guys offer and how superior it is.
