I bought an invitation kit with invitations and response cards. My reception and ceremony are in the same place, so at the bottom of the invitation, I just put "reception to follow" and am not planning on having reception cards. I'm planning on using the reponse cards for a traditional RSVP (although the knot's website RSVP function would be so much easier, but I want to give the impression that my wedding is semi-formal, and traditional RSVP is more appropriate, right?) On the RSVP cards, should I give them both the option of RSVPing on the knot website OR sending the card in? Even if I ONLY do the traditional RSVP, I want to include the wedding website somewhere so they know where to get info. Would it be ok to put it at the bottom of the invitation, spaced down to the bottom, after "reception to follow?" I would have to give them the password too. Or should I put it on the RSVP card that they will send in? Or should I include a separate card with the wedding website and password?
