You can be sad, but a lot of us simply disagree with the part I bolded. No one knew anything in mid-March when that promo came out. To say Disney knew they wouldn't be open is simply wrong. No one knew. The models were all over the place. The politicians were all over the place. The doctors were all over the place. In a lot of ways they still are. There is still a huge amount of uncertainty. So claiming Disney knew in March they wouldn't be open in June is so unrealistic and untrue many of us challenge it.
As for the rest, I empathize with the DVC folks, especially renters, because they are sunk. Thats a legal and contractual issue with timeshares. But cash rooms aren't getting 2 weeks notice. The resort is closed indefinitely. And has been for weeks. So there has been weeks of notice that it is closed. Disney is clear about that. They are also clear if you want your money back, you can have it (except DVC). Just ask. But if you want to keep hoping and praying and wishing on a star, you can, and maybe it will work out, but you were notified that they are closed way more than 2 weeks ahead.
I get being sad, but you aren't getting 2 weeks notice. You simply chose not to listen for the last few weeks and hoped what Disney has said and is still saying, won't apply to what you want.
Be sad, but don't come in and make accusations in your sadness that are simply wrong.
