Donation in lieu of favors

I need some feedback from anyone caring to provide one....

We're considering donating the money we would have spent on favors to 2 charities that have helped our families. We'd place a card at each place setting "In lieu of favors, a donation was made to......".

It will serve as a double purpose for us - resolves the favor issue in a meaningful way and allows us to acknowledge the memory of my late mother and Paul's late brother.

Mark, Dorothy & Flash - thanks for the feedback! The closer the day gets the more I seem to be second guessing myself...worrying about 'expectations', etc... (I'm assuming this is normal?)

Thanks again for the peace of mind. : )
