What's the backstop for the counties declaring bankruptcy? Given I don't know what's what here, but I wonder if either of these counties could then apply some sort of out-of-county tax to Disney visitors to make up for this? Like say they work with Disney and anyone who doesn't live in those counties pays an extra $10 on their ticket. I think I read the estimated additional tax cost was around $250 for the average family/year.
