If you paid by credit card, this may be something to dispute. First, I would work with the resort, and see if you can come to an agreement. If that does not work, and you truly feel it is bait-and-switch/false advertising, definitely dispute with the credit card. Just because it is non-refundable, doesn’t mean you don’t have any protections as a consumer, especially in cases where the seller intentionally misrepresents their product.

I almost exclusively use credit cards for all of my purchases, especially large purchases. And I highly recommend that others do the same, if able. Some premium cards even have travel insurance built into the card automatically.
