The North beats the South in this one. The outlet here is closer to you if you are staying on the south side of the strip but if you can, make the trek up to the North outlets. It has improved a lot since I last came when it was the BELZ outlet center so it's getting there but not up the standards of the north.
The shops are pretty plentiful. Remember to check in at the guest services center for a free coupon box. (Could be handy if you plan on splurging) The whole complex is a mish mosh of stores. Not as high end as the ones in the North but there are some decent ones. There seemed to be a lot of empty shops as well. Get your walking shoes on because it is one LONG straight path from the top to the bottom. If you want more shopping, there is an outside promenade with some more shops!
So get your shop on. It's aite but if you have the time and the money, I'd hit up the north ones afterwards or instead.
