I see they have set up a new Tropicana Advantage Card at the Tropicana and River Palms with a 5 card tier system. For vp, $2= 1 point and $1,000 coin in will give you a $1 cash back. No details on comps. I believe this new card system will roll over to all the Tropicana properties eventually. http://www.tropadvantage.com/
I read that they have a new outdoor concert arena at the Riverside. It is located on the garage. I have not seen it yet, and the first concert is coming up soon.
That is all the news I know about.
