That would irritate me as well! I think that you should remember that even if they did not RSVP they are still making YOUR wedding! The fact is that a DW cost them more money than they would spend on an AHW. They are there to support you! I would say that if they booked and paid to come to your wedding, you should make them a bag. I dont think that it matters if it is on the "down scale" but I think that they should def get one so they dont feel left out! Believe me, I know that there is a lot of planning in a DW, but remember the economy isnt great right now and I would appriciate those who even made an attempt to be there!
