Invitation dilemma

I ordered our wedding invitations from Shutterfly Nov 29th, I was supposed to get them Dec 4. I did a chest with a Shuttefly rep who said they were on the way and I should get them Dec 7th. Well it came and went, I've had many chat sessions and even got a $15 gift credit to my account for a future purchase. Dec 23rd I got an alert that my package finally left Atlanta and was in Greenwood IN. Perfect they will be here before the beginning of the year. No, they went to Orlando and have since been there a week with no movement in sight. Would it be tacky to create a Facebook page for our wedding? We have 90 days left and want to start getting a head count. It will be less than 20 guest not including the bride and groom.
