I'm not entirely sure about the tickets because we bought them through the military instead of through Disney and since the ITR office is closed, I can't communicate with anyone, however, I do have a decent hope that once it does reopen they will be able to extend those for us. I thought I heard something about the value of military tickets never expiring, you just have to pay the difference, but I'm having trouble finding that info again, so maybe I'm misremembering.
The DVC we spoke to a couple of times and basically told us so far, no luck unless we had been booked for those initial dates back in April/May, I think. Our only chance of seeing a refund there would be if Disney closed down again during the time we were supposed to travel. It is a $1400 loss, but I'm starting to think it might be worth it. I guess that's what I'm trying to decide. Is losing that worth it, with all that's going on as far as health concerns + the scaled back experience at the park.
