There's lots of fun to be had at this pool (or should I say pools?)! You can catch a wave in the wave pool, relax on the lazy river, unwind in the hot tub, or just take a swim in the traditional pool. There are an abundance of lounge chairs, perfect for soaking up some rays. You can also rent a cabana if you have a love-hate relationship with the sunshine.
There is also a fake beach, which I'm assuming is usually full. There are accompanying outdoor showers so you can wash off the sand that will inevitably find it's way into every crevice of your body.
Obviously drinks and food are available as well, and there are plenty of wait-staff on patrol (look for the red bikinis).
You do need a room key from either the Four Season, Mandalay Bay, or The Delano to access the beach so make sure you have that with you. Don't forget to bring your sunscreen! If you want to buy it at the hotel it has some ridiculous price tag ($16 I think). Also, flip-flops or sandals are a good idea. The sidewalk/sand can get pretty darn hot.
