Ok maybe this is dumb question, but I was reading through the perks book last night and it stated that for the discounts I needed to present both my membership ID and my Keys to the World card that states DVC owner.
I have my blue member card, but what is the keys to the world card?
During my last visit, CMs were more interested in seeing my actual DVC membership card than my KTTW (especially the case for valet), but it is good to have both.
