Limo/transport question

My wedding will be on a Saturday day, starting at 12 ending at 6 (ceremony->reception) and its about 45 minutes Away from where everyone lives..
Am I right to be thinking we need two limos to take the bridesmaids, myself, and my mom in one and the groomsmen in another? No one would really be 'seeing' us come out of the limos but FH and I don't want to see each other beforehand .. It doesn't make sense to have everyone take their own cars right? Especially since I want the girls to all get ready by me?

Also, do I not place FHs parents in the limos? Do they go separately?

Yeah, I'd have to agree that you're going to need two limos since you're so far from the site.

My FH parents are going to have to transport themselves..and so are MY parents. This way they have a way to get home at the end of the night without having to hire anyone! So I'd say let FH's parents take their own car!
