Jim... I was there last week and they have the green room keys that look like the slot cards and actually have the same printing on the back. Word is the room keys would be useable in the slot machines sometime soon if not already.

The slot cards are a newer issue then when I was there 6 months or so ago. The text on the back has changed slightly. The next to last line on the purple cards is now aligned with the text above. If you can get any higher level cards with this change let me know, I can use them. They would only give me the purple Preferred cards.... Bob
