I would not expect David to have millions of dollars at his disposal. His $4.50 cut has most likely already been spent on business expenses (including wages to his staff) and dividends to the owners. The only cash he has is the 30% due to the owners, but this is offset by the liability of making these payments once check-ins resume at the DVC resorts. Depending on how long the resort closure continues and the success rate of credit card chargebacks, it may be in David's best interest to declare bankruptcy and move on - there is no alternative once the chargeback amount exceeds the 30% held in reserve, he would just be out of cash.
I don't know how each
travel insurance policy works, but on my Chase Sapphire Reserve card, which I am using to charge travel expenses, there is an explicit coverage for travel interruption due to airline or
travel agent insolvency. With such a clause, there should be much easier for renters to pursue a successful recovery of their expense. Hence I am beginning to wonder whether a sooner rather than later David's bankruptcy would not be best for everyone involved.
