Both of our parents contributed financially to the wedding. As a thank you, we are taking them out for our "rehearsal dinner" to the Eiffel Tower restaurant the night before the wedding. My fiance mentioned last night that he was wondering if we need to get them an additional gift/momento/something else? I was kind of thinking we might send them each their family portrait but I didn't think of anything beyond that. Are you guys doing anything? Is this even necessary? Seems odd to spend money thanking them for...giving us money.
