GAGE COUNTY,
I have never used these passes, but I am familiar with what they are, and from what I've heard they aren't effective at getting you in any faster than just standing in line . . . but if you do choose to use them, please let me know if this information is erroneous.
If you and your friends are going with several women (at least a 1:1 F:M ratio, a larger ratio would be even better, and the more attractive they are even better still) and present yourself as a group, then you will not spend much time in line, period. However, you'll still have to pay the cover charge.
If you're not going with women, maybe try to meet a few either during the day or while standing in line and suggest that you go in as a group, but by no means imply that you will also be hanging out with them the rest of the night; they just make it easier for us XY's to gain entry (I know, I know. . . easier said than done, huh?

) But a few of my buddies have actually been able to pull this off, which beats standing in line for what could be 2-3 hrs on a Friday or Saturday night (eating into your time at the tables!!)
Shadroch is right, many of these "passes" have time constraints for entry, and the free "drink" may be a Red Bull, at best.
Yes, at many clubs there are separate lines for VIP, usually for people who have reserved bottle service or are on the guest list. There are a few ways to get on the guest list, but one of the easiest is by contacting the VIP host at the particular club . . . you can find this info on
http://www.JackColton.com, which is a pretty good website.
Other means to get inside faster if you're not on a tight budget include greasing the bouncer/doorman (anywhere from $20-$100 depending on the club) or just biting the bullet and reserving bottle service, which can be pricey, usually a 2 bottle minimum, more for larger groups, with bottles starting at around $300. But this ensures that you won't be waiting to get in, you can stay all night in a private booth, and have access to all areas of the club (some areas are closed off to the rest of the clubgoers). I don't suggest bottle service if you plan on hitting up a few clubs in one night.
I also don't know what to wish for more . . . that you have a great time at the clubs or draw great cards!!

Hope this helps.
