Yes, unfortunately every certificate in the pack is marked with your name and OnePass number. Also, ticket agents are usually very careful to match the names on the certificates. However, when I purchased the pack, I also immediately purchased a President's Club membership, and therefore did not need the 2 passes included with the pack. So, I gave them to a friend and he was able to use them. Apparently they just took them and marked them as used.
