I disagree. Bachelorette parties have several great uses if you know how to go about interacting with them properly!
Pivots: They make GREAT pivots and the key to using them as pivots is the same as using any girl you just met at a venue; be aloof. Don't treat her like she's special, remember that you're the prize and just treat her like a cool girl that you don't mind having hang around you and keep her laughing, flirting with you openly and obviously attracted to you.
It doesn't matter that girls don't typically hook up at bachelorette parties, because you're not trying to hook up with her, you're just treating her like one of your little sister's bratty friends and using her to demonstrate solid pre-selection. If you do this well, then you look amazing to the other women because if you're an entertaining guy you can walk right into a party and end up with 3-5 great pivots in a matter of minutes that aren't interested in hooking up with you, but that think you're such an awesome guy and are having such a good time, that they do everything they can to find and hook you up with girls "worthy of you".
Pumping you up: This is one of the best things about bachelorette parties as far as I'm concerned. They CAN make great pivots, but you're not always lucky enough to find a group full of nothing but hot chicks, but regardless of how they look, bachelorette parties that you meet at the club are almost always a lot of fun to be around because they're having such a good time and they're full of so much positive energy. That means that just by being around that group you are going to feed off of their energy and get pumped up yourself.
More than that though, they're drinking, they may even have a list of naughty things for 1 or more of them to be trying to fulfill during the night and you can participate or find them some other sucker who is willing to give them their boxers instead of you. A lot of them will dress up in sexy outfits or play pranks or any number of fun things that you can get involved in with them for a little while. They're almost always really accepting and so any newbie can go hang out with a bachelorette party and feel like a rockstar for 15 minutes. Doing this can totally kick your energy through the roof and anyone who knows anything will tell you that having good energy is more important than I can put into words.
So you walk into the club feeling good or maybe even kinda tired or something. You hang out with the bachelorette, maybe you make out with the bachelorette (that's always fun!) and you walk away feeling like the coolest guy in the place and suddenly you ARE the coolest guy in the place because of the way you feel and the way you're carrying yourself. You start chatting up a 3 set of the hottest chicks in the joint and you tell them some stories about the crazy party of girls you were hanging out with and suddenly one of the girls from that group walks by and runs over to kiss you or hug you or do something that makes you look really good and now you've got those 3 girls hook, line and sinker.
So sure, you can avoid bachelorette parties and stay "as far away from them as possible" or try to make them come chasing you, rather than making them think you're the coolest guy and then having them make you look that cool for the rest of the night. That's totally your choice, but personally when I go to the bar I make it my mission to run the place and have as many people know me and showing me social proof and pre-selection throughout the night, so I personally don't see any reason why I would avoid securing one of the easiest groups in order to make it even easier to build that social proof from the start.
No one is beneath you, no one is of no value. Everyone has a place that you can fit them into, a purpose that you can find to use them for and a way to have them help you succeed. I make nice with bums because no one will ever think less of you for being nice to a person or knowing lots of people, only if the only people that you know are the people at the bottom. If you only know people at the top though, it can look like you're an arrogant jerk and that you think you're better than other people...which in that case you probably do and they're judging you right. So don't be a biggot, broaden your horizons and show everyone that you're the social center of the universe and that bachelorette party is a great place to start.
