They have gotten much stricter with the TIW. In September, I needed to show a picture ID almost everywhere I used the card. They would not even accept my KTTK. They said that too many people have been loaning their cards out or even renting them out, so they are stricter now and enforcing the rules. As for the extra card, we had one the first year, but we realized quickly that it was a waste of money, as we were almost always together.
