So I have been doing some research into this joint party thing, and found a couple things:
This first one came from:
http://www.mywedding.com/blogs/mywed/2007/03/how-and-why-to-throw-a-joint-bachelorbachelorette-party.html
This one goes over the who, what, when, where, and why's of the process for those who do not understand that not everyone wants to suck on penis straws, and do jello shots or have some non self respectful nasty stripper crawling all over them!

This one just gave some ideas of what you could do.
A blog that I ran across mentioned renting a boat, and cruising around the lake or river, and maybe doing some skiing or wake boarding! That would be a fun idea!
Most of the ideas that I am getting from friends are still splitting the party up, which I wouldn't really mind, but I want to do the fun stuff the guys do too! Like paint ball, or go karts, or laser tag!
This is going to be a challenge!
My shower will be in the morning while FH and his guys go golfing and to the shooting range.
That evening, we're having a Jack and Jill/BP Meet & Greet at Dave and Buster's/
Lastly, that night we are all going out as a group.
Hope this helps!
