Hello! My future sister-in-law has graciously offered to fully host our rehearsal dinner and our welcome party. We were initially looking at a more affordable rehearsal dinner and a non hosted party to fit our budget, but she wants to go a little nicer for the dinner and fully host the party. She wants to do this partly because she knows traditionally the grooms family pays for the rehearsal dinner and their mom as recently passed away so she wants to do want she knows their mom would. We're obviously super grateful, and I wondering if we should acknowledge her in some way? Or if we should send a thank you gift?
Also would love any pre-emptive advice how how to make sure she doesn't go overboard without sounding ungrateful! We have different styles so we want to carefully navigate making sure this party still reflects us as much as possible.
