Trop and the Taj run tournaments on saturday. The Borgata for some reason doesn't run weekend tournaments that I am aware of anymore.
There's 2 tournaments on saturday at each the Taj and Trop. Taj has a $100+20 around 11am, and I think a $300+xx around 6 or 7pm.
The trop runs something very similar. It's posted on their websites.
