That's good to hear. I'm glad that WDW is trying to stop the loophole for people scamming the system.
Just to be clear so as not to be misunderstood. We were staying on site and did have our room keys with us or we would not have been able to enter the park at all. We had a package with our tickets on the key. We were not trying to scam the system but Disney did not seem to be bothered by those that might be. For all they pay attention people could be bringing back old key to the world cards to get entrance as well because they do not look close enough at the cards to read the dates on them. We have always stayed on site with a package so no need for us to try to scam the system.
