An adult family member suddenly died. He had a zoo pass. Can that pass be transferred to another family member?

Although do not currently know the answer to the o.p. I can find out on Tuesday and report back. As to the response about anyone using the passes, that may have been the case in the past, but for the past three weeks I have both witnessed other pass holders being asked for ID and I have been asked for ID when showing/scanning my annual pass.

Honestly, they don't check IDs. All they do is scan that card to say that a pass holder visited that day. So technically anybody can use those passes.
