Just a few thoughts:
Get someone (With some experience, if possible) to record the ceremony using a tripod.
Maybe, with permission, have a practice ‘shoot’ in the church or wherever it is to take place.
Do not ‘Pass it round’ unless you want to end up with a lot of unwatchable rubbish.
One keen, dedicated and sober, video-photographer maybe best.
Use a mini-tripod on the table and or a monopod if a normal tripod is not possible at the reception.
Slow panning is possible hand-held, but static hand-held recording is a No-No.
Discarding dancing camerawork during editing is no joke. I have been down that road when my second cameraman decided he didn’t need a tripod for close-up shots when recording a concert. I do not think he will do that again after the xyzw&%+xyz I gave him!
As with everything, preparation and a little research pays dividends in the final outcome.
Wishing you A Great Day! and A Great Life together!
I’d second what Mark has said, “So I'd get that HC7”.
The HC7 will take your 6 megapixel Still photos on the honeymoon too!
