Best way to map destination parking spots perpendicular to the side of a way?

I'm aware of parking:lane:side=perpendicular, however for cases where the parking is at a specific destination rather than the side of a regular street it isn't so obvious to me whether I should be mapping the parking as an area or using this key/namespace convention.

Here are two links to locations where it isn't obvious to me whether the parking should be considered a lane or an area:

1. Here I've mapped the parking using the namespace/key combination.
2. Here the parking is mapped as an area and I'm currently debating if I should change it or not.

I lean toward using the namespace/key combination again, but I'm unsure (I think the lack of spatial representation is what makes me hesitate) and thought I'd seek more experienced advice.
