I had spoken to a friend prior to my trip to Vegas last October and asked him what I MUST do in Vegas....and he pointed me in Vegas Rockstar VIP's direction. I had SUCH a great time. We did the Friday night one and it was AMAZING. We loved all of the clubs we went to (good music and fun crowds), particularly the first one (wish I could remember the name because it had a great drink special). Our hostess was AMAZING. I agree that the rides in between the dance clubs are short, but she kept our drinks coming non-stop. I was thoroughly buzzed all night long...which is probably why the only place I can remember was Paris (great views!). This is something we will definitely do again if we return to Vegas. Well worth the $. I spoke with my friend and did notice they go to different places depending on the night you book (so that is something to keep in mind).
Disclaimer: we went in October and had no problems (nor did we have to pay any entrance fees to clubs). Some of the more recent reviews would have me worried to try this again.
