melady24 - thanks for sharing the link to your Arrecife photos. You look beautiful! The pictures are great! I'm so excited.
I'm in the process of putting together the key card holders now and I was hoping to not have to personalize them. :-) Because there are some people who still haven't booked their flights yet. I was hoping since there are different colors then they can keep them straight. Also, I can't decide if I will print something on both sides (don't really know how to design that) or just one side.
As for the key card holders, I printed on one side and just did a cut out from the white cardboard for the back thinking it will not show through, but lots of people just removed everything from the holder and just used it clear. But that's just preference, I prefer for people not to see into key holders, others don't care. As for colour - I was not able to get diffirent ones, so if you can, it should work. As a matter of fact, I just used a hair clip on mine.
