The first vacation my now husband and I went on was to the DR and we LOVED it. Great choice. And don't feel to overwhelmed about all the stuff you can find on here, b/c it won't end up mattering as much as you thought. There are SO many of the little things about my wedding that I realized late in the game weren't necessary. They were more work then reward. Like the OOT bags, I sewed my own which was fun and cute, but then I filled them with junk instead of one or two nice things. I regret that. And the guest book too. We only had 20ish guests so the book looks silly b/c it's practically empty! Anyway, my point is that you will find a zillion and one ideas on here that you want to do, but you can't do them all. The ones you chose to do, you will have plenty of help here!
I just wanted to say that I love this post!
