Would be the best bet as then you can truely enjoy the event and not worry at all about babying the camera
If you MUST use a DSLR then buy an old K10/or even a *ist-d if it definately won't rain - put a cheap old AF zoom on it / put on a UV filter and hood (cardboard tube (doesn't need to be pretty) and tape up the camera mount. Also let it die.
Sometimes sacrifices have to be made for great photos, just think who else will be that crazy?
