I have covered several friends' weddings as well as being a guest.
Relaxed, friendly, professional, speedy, efficient.
Employ professionals; doing things on the cheap always shows in the results.
A friendly approach to get people as relaxed as possible.
Bride and groom relaxed and happy.
Bride on her motorbike when driving; meant I had to hang out of a car window whilst driving.
Plan ahead; ask your wedding official if it's OK to stay indoors after the ceremony, and where are the best rooms at the reception to accommodate large groups (stairs often best).
A hobby that went mad.
