Yep I agree with everyone else, do a gift registry at Myers and you can nominate your gift card amounts, then just note the registry # on the invites. For the children, we wrote 'Adults only reception but we can recommend some fantastic babysitters' but I was lucky enough to know a lot of girls through work who were able to babysit. Good luck - and as long as you prepare yourself for the fact that someone will always have a whinge about some aspect or another, but it's your day and you can do it exactly as you want
