In my group there was a couple in which the husband was never able to attend a post session. The wife went by herself with a camcorder and recorded the entire session. Then they viewed it together later in the week. She said she got a lot more out of it by sitting through each session twice. So you could consider doing something like that.
To get the Post session materials you will need to contact the Post host couple. They will have everything. The contact info for that couple should have been given to you over the weekend.
