My heart goes out to you as well. We faced the same thing with my hubby's father. Unfortunately, dh's family is in Australia, and we are in MD. We were not there for his passing, and I'm upset that he never got to meet his grandson who is his namesake, and see his 2 granddaughter's again.
We're bringing my hubby's mum over the Christmas holidays, and we are all going to WDW. It will be sad for we had planned many times to go with his mum and dad, and never got around to it. Then he was too sick to go, and then he just passed.
I have all of you in my prayers.
