Monday my grandmother's husband passed away and the funeral is planned on the same weekend that my friends are getting married on.

I've known my grandmother's husband for basically my whole life. I've never bonded with him but I also have never had any trouble with him. I only want to go to the funeral to be there for my grandmother.

On the the other had I already bought plane tickets and a hotel room a month ago for the wedding. The total price was about $350. I also agreed to help pay for the bachelor party. I can't  get refunded for the tickets and hotel.
