Agree, either make sure you recall that your wedding party are guests.
OR, conversely, do what I did, and what some of my friends did with my DH and I for their weddings, and very intentionally appoint a best man and a chief bridesmaid to fill the roles in a very interesting way - i.e. as stress-and-fuss-managers, almost in the role that a wedding planner would fill.
It worked exceptionally well, because it meant all the mither of clock-watching, guest-wrangling, venue-liaising etc etc fell to two people NOT the B & G, and from neither family, who were instantly identifiable by outfit. For us, and for our friends, it meant that Bride and Groom, and MOB, and MOG etc could sail around serenely like swans all day, whilst the frantic paddling was done by two other people, who were not as emotionally invested, had no axe to grind and no pre-exisitng bias, who were trusted to do it - and key here - knew they were going to before hand.
The large bottle of champagne at 9pm, when everything's settled is most gratefully received as well. :-)
Other than that, so what you want and make sure you enjoy it. If you do, and you remember that your guests are people, it'll be fine.
