Is this an inappropriate request?

I m getting married and one of my friends wants me and my soon to be husband to give her a ride to the reception and home afterwards. Personally, I think this is a major no since it's our big day and we aren t really supposed to be chauffeuring people. The reception is 20 min away from her house, and she lives with her mom and bf that can drive but for some reason won't. I think her bf is irked that he's not invited (he's super creepy, lazy, and hit on me a couple of times...guy's a jerk). Am I wrong to tell her to find another mode of transportation?
