Girls, What is a good water proof mascara that is easy to get off and will not damage my eyelashes?

I am attending a wedding, and so will need a good water proof mascara. I don't wear this everyday, and have heard that it is difficult to take off and is hard on the lashes. I wouldn't think that one day would damage my lashes, but how would I get it off? Is there a good one that is a little easier to take off? If I wear my regular mascara, I am certain that it will "run" during a wedding. Please help. Thanks.
