RSVP Wording for Cruises?

[lovepea]

I have been going back and forth regarding sending the RSVP cards.  Since we aren't doing a traditional, formal wedding, I was hoping I might be able to skip the RSVP cards, especially if they don't get used.

Has anyone gave thought to sending Evites versus regular invites? My daughter didn't want to waste all that money on invites which most people throw away and then the rsvp cards knowing that only a handful of people would be able to do a week long cruise. So we used Pingg.com and sent the evites to everyone and they keep track of your R.S.V.P.s most are free but we paid the 10 to have the "envelope" open up and stuff lol plus you can make a free wedding website and all threw them if you choose.
