Logistics?

I'm trying to figure out the logistics of getting ready... My venue is a restaurant with halls, so they don't have a bridal suite, but the coordinator said that there are offices we can wait in so nobody sees us while people are filing in. So I'm getting ready in my hotel room, which is about a 10 minute drive from the venue (my parents will be driving me). So now my question is... Should I get fully dressed and risk messing up my dress in the car, or should I just do everything else first and get dressed in the office? I kind of wanted to see the full effect before leaving the hotel, as I'm not even sure if there's a mirror or anything in the office, and I was also hoping to get a few individual shots before the ceremony (in the hotel but also outside near the venue). But is it bad to travel wearing my dress?


Sorry this is long and complicated, I'm trying to build my timeline and I'm really not sure how to work this out and I'm the kind of person who's always running late getting ready so I want to make sure I get the schedule right to avoid that! Any input would be greatly appreciated!
