I didn't know the ToC in detail, but I guess there is a section which allows to cancel reservations when guests also can cancel them. And as you didn't buy a package of flight + hotel, the flight is up to your risk. So, the best strategy is indeed to try to get a comparable room somewhere else. Potentially with the help of a lawyer.
