Depending upon your bankroll, time and future casino plans, you might want to go for Diamond in a Day at Harrah's. If you have a good run at the tables you could add that to whatever you earn on VP or slots. It's 3000 points. (30k ci VP). Now, unless you were planning to get back to AC within a month or two, you couldn't redeem any bounce back cash or future offers BUT, you'd have a Premium Slot card that you could show at the Borgata to get upgrade to Black Label there, and get $100 in fp, entrance to the lounge there and I think 1 or 2 nights (which include Fri and Sat). Diamond gives you rooms in LV and free show tickets and entrance to the DL.
If you didn't want to do DIAD at Harrah's, you should do it at Bally's.
There's also other new player offers in AC. I believe there's one at Resorts and Trump Plaza. There's also a new casino in AC called the Revel that is supposed to open April 2.
Now, you might generate offers good enough to justify coming back to AC so you'd have to think about whether or not that is even possible.
My subscription to LVA runs out at the end of this month and I'm not renewing. But, you can reach me on the other board or PM me with your email address.
