Boy, do I agree that it is confusing (and inconsistent I might add). I agree that members only might be the easiest and fairest way to split the hairs, but I doubt that will happen with most perks (nor does it probably matter with most of the perks--the dining and general recreation discounts, for example, still have the intended goal of drumming up demand for those items regardless of who uses the discount. I consider them less of a perk and more of a marketing device for a subset of activities, whereas things like the annual pass discount, free valet parking, and pool hopping probably fall in a different category in my opinion).
