My DH and I are both lawyers, and that is not contract law. No one party can unilaterally change the terms of the contract after it has been agreed to. The reason Disney can get away with modified experiences is because the contract specifically allows for that, but it also states "Prices are for the total package and cannot be broken down into individual package component prices" with the only exception being "Prices are also subject to change due to modifications to package or package components"--so disney cannot provide less than the total package without changing the price. Which is no doubt why they gave the 35%. Whether that is an adequate price reduction is subject to debate, and something a finder of fact would have to determine in a legal proceeding.
Also it is not true that Disney only owes a refund. The legal remedy for breach of contract is "expectation damages." That means that the if Disney is in breach, the customer should get the fair market value of what
they expected to get, not only what they paid. The reason for this rule is pretty clear: it would allow someone to get out of a bad bargain: e.g., I offer to sell you a priceless Van Gogh painting for $10; you accept and pay $10; I realize that was a mistake and refuse to sell it to you--your damages are not $10: they are the value of the painting you didn't get
. In my case, I paid for a room, tickets, and dining. A refund would only refund the room and ticket cost, and not give me the full value of my package.
Actually, they absolutely could deliver on the promise. The restaurants are open. I can eat at them. They could give me
free dining at the restaurants that are open. Nothing is stopping them from giving me dining credits like they would for the dining plan but for their own choices. It is not as though they dining plan
can't exist--they could apply dining credits at the push of a button, but won't.
I think I should have been clearer I meant
dining credits, not room credits. They could absolutely provide those, just as they have done every other trip I've been on where I had the dining plan. We won't have a rental car, so eating off property or making a grocery run is not practical. As long as they have quick service restaurants open, food can be grab and go and seating capacity limits are meaningless. We can take our free meal and eat it on a bench.
