Not even a friends wedding? Once the obligatory crap is out of the way (ceremony, dinner, photos) they're a lot of fun. At 10 you'd have probably missed out on a lot of that since for adults the booze is a lot of it. But funny you say that, at ours we had a giant box filled with silly props we'd made and a bunch of cheap toys etc like lightsabers for the kids and adults to mess around with in silly photos etc. The adults loved them too, we have so many photos of even 50+ year old people messing around posing with sabers and silly face props, like Mario's hat and stash, that gave us a lot to look back at that we'd missed on the day, plus the kids had fun all day long.
The kids and adults alike took most of the props and toys home then we gave the rest to a nursery school. I'd highly recommend thinking of the kids too if you do ever get married. It also takes some weight off the parents so they can enjoy themselves more.
