Originally I was going to skip the limo. We are having our ceremony and reception at the same location, so I didn't really think we needed a limo. But now I am thinking it would be nice for the entire bridal party to ride to the venue together.
The only snag in this idea is how everyone will get back to where they need to be after the reception? Do I have to rent the limo for the entire day? Do the limo companies split the time (one hour before and one hour later)? I think that figuring out this transportation stuff has been the most challenging aspect of planning this wedding!
FI was a best man in a wedding last year and this is how they did it: Bride and DMs rode in the limo to the countryside chapel. I took the groomsmen in my car. The wedding party rode in the limo back downtown Louisville to go the reception location. I drove in my car, got lost in the country side and couldn't contact any of the bridal party for help, called my mom pissed off and crying and she was able to calm me down, lol. This is off-topic, but a funny story. Earlier that day or day before, some of the bridal party took their cars to the reception location and left them there so that after the reception, they had their cars in the parking lot.
Good luck!
