I'm so sorry. Canceling a trip, especially one you've been planning for so long, is never fun.
I agree with everybody who said to try to call and get refunds - you'd be suprised how helpful most people are and the worst they say is no. My grandmother ended up hospitilized with a stroke 2 hours before DH and I were supposed to fly to Vegas. While I sat in the ER with her, DH made phone calls and the airline, hotel and show tickets all refunded our money in full. The money wasn't what was important at that moment, but it definitely helped to not have to worry about - and we were able to rebook the trip for the following month.
