Sunday wedding timeline

Me and my FH are having a Sunday wedding, there will be out of town guests (family that will be coming over 24 hours before the wedding) and we want to make sure that we have enough time to get ready, and also end the reception early enough for guests to arrive back home for work etc. the next day. We are planning on getting married around 1:30-2:00 pm and will possibly serve brunch foods at the reception? We want to make sure people have enough time to relax and have fun at the wedding but also enough time to head home as well. I know many people leave Sunday weddings early anyways so we though ending around 5 or 6? Will this be enough time for people to feel like they have actually been at a wedding and to drive 2 or 3 hours back home? ( we are in college and getting married at the halfway point of our hometown/where we both live). We have access to the venue through 8 am to midnight and the ceremony and reception are held in the same place!
