Parents gifts-when to give?

We are going to take my parents and fiance's dad out to dinner a few weeks after the wedding. The dinner will be part of their gifts but it will be a thank you as everything dies down. It will be more private that way. I know you're getting married Sunday so a dinner beforehand might be difficult, so maybe after the wedding? Or I think giving them as you see each person would be fine. It also depends a bit on the moment you want to have wih them. It might be rushed if you give it to them at a random time when you see them!

You could pull them aside privately at the party and give them to them that way.

I think giving them a gift ahead of time or after the wedding is fine, but if you wanted to do it at the rehearsal get-together, you could always ask them to all come a little early and do gifts before anyone arrives.

I think that's perfectly fine. The gist is giving it to them, doesn't need to be during your party.

We're making our parents, and FHs grandma, Shutterfly books once our pictures come back.
