Formal Invitations - to send or not to send?

[sdj327]

I am doing boarding pass save the dates with a link to our wedding website. I am going to have guests rsvp thru the website. I needed to get the word out asap and by the time formal invitations would be going out, most people will already know if they are going or not.

I have already told most family the traveling info informally so we have decided to just send out the invites and skip the save the date

I did formal invites but well after sending out online RSVP invites.  I didn't originally want to do them, but I figured one day I'll want to look back and have them as a memento.  However, I'm less than 2 weeks from the wedding and I still have a batch to send out....hhahaha!
