No Dance with Father, as he is dying with cancer

Ok, I have been waiting and waiting in hopes that my father would be well enough to make it to my wedding. It is less than two weeks away! He was diagnosed with Pancreatic cancer MArch 30th, and it has spread very quick. We moved our wedding up 6 months to have him here, yet now he is already in hospice care at home and cannot get out of bed. My mother will not be attending as well, as she cant leave him. What could I do to honor my father during our "dance".... I want to do something?? Any ideas
