The math

Regular adult admission at San Diego Natural History Museum (The Nat) is $24.95, so timing the visit to the free window keeps $49.90 in a couple's pocket and up to $99.80 for a family of four — each month it comes around. That's what San Diego City & County residents, active military + dependents leave on the table every time they pay walk-up prices. The catch is capacity, not money: free slots are reserved in advance and the popular dates go first, so the reservation is the real currency here.
