Just a word of caution if you decide to leave the favors in a basket for the women to take as they leave. I've had it happen to me more than once where people were supposed to take favors, but just didn't notice them or didn't notice the sign directing them to take them. Then I got left with a whole bunch of untaken favors. If you have people helping you host, it might be good for that to be someone's responsibility to "push the favors."
Just make sure the people take them! And have fun with your shower :)
