How can I honor my father (who is sick and can't make my wedding)?

I think your idea is great! Maybe have the dj explain why he is isn't there

You can still do the slide show but include a slide at the beginning with something like "For my dad who would be here if he could".

The slide show is a great idea. Have the DJ announce the situation before it starts. If it is possible and won't upset your Dad too much, you could have a picture taken of you and him with you in your veil or even your dress as a final picture for the presentation.

Will having the video presentation only sadden you more that he cannot be there? Otherwise, I love that idea!

The video presentation is a wonderful idea.

My mom wasn't able to make my wedding, so I dedicated part of my speech to her. That's it. Everyone pretty much knew what was going on, so when I started to speak of her, the whole crowd stood up and clapped for me. It was heart-wrenching, but SO loving and amazing at the same time.

Actually I am going to take the opposite view of most other people here I would say skip the slide show I know if I did not quite catch the announcement I would be very confused and think he was deceased. If you are planning a first look could you maybe do it in a park and then the two of you go by the hospital and take a pic with you dad? Then when you do the father/daughter dance have the pic you took projected on the wall or something?

Thank you for all the great advice

I think Mrs. Drakthal has the best idea!
