Our first Disney trip is coming up in 27 short days and my father in law who has Leukemia has begun to take a steady decline over the last few weeks. As hard as it is, my husband and I have started the "what-if" talks just in case we have to call off the trip last minute if he passes away. I'm so unsure of what to do. I just bought travel insurance through Allianz - hopefully I don't need to use it - but if we do have to cancel, how do we even begin to reschedule? We've been planning this trip for over a year and I don't even know where to begin to re-do everything or if it would even be possible to do on short notice so that we could still go this summer. I'm also worried about the travel insurance coverage. Has anyone had to deal with this at all? I'm really struggling to even get excited and trying to figure out how to break it to our kids that there is a possibility that things may not work out to go. 
Thanks for any advice.
