At first we weren't going to do OOT bags as we thought it would be a lot of work and an expense. We are just having a small wedding and most of the people haven't travelled much before. We thought it would be a nice idea and gesture for out guests to make them feel more welcome. We aren't going crazy on them, just including a few things that we think they will actually use or not bring themselves. We don't want to have to use all our suitcase space on OOT bag things. Because we are a small group, it ends up being less then $10 per bag. I don't think you have to do them, its totally up to you!
