Hey PJ. My wife and I both received a new stay-and-play offer from M Resort in the Penn Play app, it's the same offer we stayed with in December. It's good from 01/03 to 02/28, 3 nights, $20/day free slot play, and $25/day dining credit, since I'm Preferred level, I get charged the $39.99/night resort fee. If you're Elite or Owners Club you don't get charged the fee, I figure you already knew that if you are Elite or Owners Club.
On our last visit we also received $25/day casino cash after earning 400 points, my wife gets the emails but I don't, and she said the $25 casino cash promotion is because we regularly play at another Penn casino. So we may get that as well when we go in February.
Let me know what kind of offers you get, I'm curious to know!
