The other possibility is that they are waiting to see what is in the stimulus bill after it goes through the House and what implications it might have for them.
E.g. the Senate bill* makes hotels with less than 500 employees eligible for loans which convert to grants if they are used for payroll, and explicitly notes that this is hotel-specific, not company specific, so that e.g. for an owner with 50 hotels each with less than 500 employees, all these hotels are eligible. However, there will be limitations on layoffs tied to accepting this money.
If they are waiting for the final bill, then the issue is do they announce before it's out a close through April 19th and continue to keep paying all through then, and then change the closure date (and pay policy, perhaps) after they have digested the bill.
