Okay, so I have been on (I think) all of thei club hop options and the breakdown is as follows:
Club Hop (Regular): you get to drink for cheap at the meeting place (not for free) and it's only $49/person; if you have over five people or something like that in your group then you ahve to pay an additional gratuity up front. You meet somewhere, then head to three additional nightclubs--you will generally walk to the first one and then be driven to the remaining two. I suggest that you do this if you're easily bored like me, or if you don't know where to go and what to do in Vegas.
Club Hop (upgrade to PURE): everything mentioned above applies except that the last club is now PURE instead of somewhere lame--not sure if this is really worth it considering you won't actually get to pure until about 2am, so you only have 2hours or less to get your groove on there. If you are one of those people that checks out early from the group then I suggest you not waste your $30 and just stick to the regular Club Hop, but I do like PURE and so I get the upgrade.
Club Hop (Deluxe): this is the one where they pick you up in a limo and it's somthing like $130 based on a four person occupancy--meaning that if there's only three of you, you have to split the cost of that nonexistent fourth person and pay up! Once picked up, you are given a bottle of champagne to share and taken to the Vegas sign to take pictures. Then you go to the Palms and get into three clubs plus Ghostbar; I believe there is a $60 pass that you can get at The Palms that gives you about the same access, but you ahve to wait in line. All the clubs kind of suck, and Ghostbar is interesting only because of the glass window in the floor that looks down 18 or so stories.
In my opinion, don't waste your time with the deluxe and only get the upgrade to Pure if you are able to stay up and out dancing until 4am.
Enjoy!
