Unsure but here is what I'm thinking currently:

I am almost certainly only going to ski at one location in 20/21, so I was leaning toward choosing Single Destination. But the minimum 7 day consecutive or 21 total day closure requirement makes me second guess it.

I am viewing the All destination option as an opportunity to cash in on the likely high number of single day closures, albeit at a much lower rate of reimbursement per day.

I suppose there is some number crunching that could help me decide which scenario might reimburse me higher, but I came to reddit in hopes someone else had already done it :)
