This was a hard lesson my wife and I learned on our wedding night. For pictures, instead of a Polaroid style camera (which I had bought originally for the purpose but we decided against it later) we thought it would be great if people could use their own phones to take their own reception pictures and then print them off a Bluetooth photo printer we brought, and then put those pictures into a photo guestbook. Instead, no one could get the app downloaded or working (well almost no one) the night of, and one person in the wedding party had to act as a technology liaison and get pictures from other people, then print them from his phone. We ended up with around 14 pictures in the photo guestbook. If we had just gone with the polaroid camera we probably would have had 3 or 4 times that many pictures. All because we assumed the technology would work as easily as we were able to get it working at home, for everyone else.
