I have a family member who has been a tremendous help with wedding planning. She hosted my shower, is making wedding desserts, made my invitations, and has offered tons of help and support. Part of the reason is that she just loves this stuff, but also to help us out because she knows we are paying our own way and she can help. Therefore though, she wont' take money from me. I decided to invite her and her husband to the rehearsal dinner (otherwise the RD is only WP and parents). So they're getting an extra meal worth like 75$ or so for the both of them. We also bought them a nice bottle of sparkling wine that was like 20$. Is that enough or should I do something else? I don't want to make them uncomfortable or anything doing too much either.
