Does anyone know if you can use Subway card rewards at KI? I have enough points on my card for a free footlong, and if I can use it, I'd like to (obviously). My assumption is no, since the prices are higher and KI undoubtedly gets a cut. But I thought I may as well ask and see if anyone knows for certain.

I don't think the places that are also outside KI (Subway, Chick-fil-a, Panda Express) accept any kind of gift cards or coupons

I know the Starbucks at KI accepts Starbucks gift cards for payment but does not participate in the rewards program connected to those cards. The case might be similar at the Subway locations.

They do not accept them at all.

Call the bark.

Actually, call the park. Calling the bark wouldn't do you any good.

Theme parks are one of the reasons why they always have the, "at participating locations" in the tagline.
