My FH made the suggestion that instead of providing RSVP cards we should have guest RSVP on our wedding website as an effort to trim cost on stationary and postage. Is this possible? Has anyone else done this? If so how did you pull it off and what problems did you run into. Also; we are having an adults only reception, I'm worried that this will cause issues and confuse people. Please provide any advice and info you have regarding RSVP cards and/or weddding website RSVP portals. Thanks WW peeps!
