Stop in for a cup of coffee

Need some advice.

as you know, my wife's grandfather passed yesterday. Originally, we were scheduled to go over there as is tradition for Thanksgiving tomorrow. With his passing, no one has even mentioned it, focus right now is on the final arrangements and his final affairs. So we have no idea if the get together is still on for tomorrow or not. If it is, great, if not, I was thinking of surprising my wife by cooking our own Thanksgiving meal for the first time ever for us, the kids and maybe her parents. I have all the items needed already. Question is, would it be inappropriate for me to ask if the family is still planning on doing the original schedule tomorrow?
Morning guys. Nothing wrong with asking. A big meal like Thanksgiving takes time ahead to buy and prepare. Many in your family might not feel like cooking where others may find it therapeutic to cook for the family. The holidays are a tough time without Grandma or grandpa. May be just order pizza's or take out if that's what everybody likes. We have a grocery chain here that sells T-giving meals right down to the pumpkin pie. Lots of options for you all.
