I agree with NewKilt and Panache. Ask the new daughter what she thinks. It's her big day. There will be plenty of other times to deal with the father of the bride.

There are many, many letters to Dear Abby and others that show where a little thing like this on a wedding day starts off a new marriage under strain.

Could also put your son under pressure if he has to decide wether to support you or his bride. IMHO he should support her. Been in that sticky position once or twice.
