Couldn't you show your ID and have them "activate" your season pass for that day, charge you a small free to print you a temp one and make you check back in when you leave to return the temp tag? When I worked in a big, high security corporate building back in the day that's what they did when you forgot your security badge. Oh, and if you forgot to return the temp badge they charged you a hefty penalty fee and if you got too many they canned you.
