Wedding Day makeup

I am having my wedding on Saturday and I am getting a little paranoid about the makeup. My photographer is coming to my house at 2pm and the ceremony is at 6:45. I am nervous that the makeup won't hold up on my girls and my mom and look good the whole night.

I guess this question is for past brides....How well did your girls and mom's makeup hold up for the night.

Should I hire the makeup artist to stay until we leave for the Hall at 4:00 to do last minute touch ups? Or is it not worth it?
