I hope you can help me with something...struggling with the decision of whether or not to include RSVP cards and return envelopes. My mom says it is proper etiquette, but I don't think I need them! I just wanted to include another pass (doing boarding pass invites) with my TA's info and "please book by..." Guests don't really need to RSVP to me...I'll know they're coming when they book, right? I really don't feel like I need to know early. Please help me decide! What did you do???
