Stayed here in the Sky Suites and really enjoyed the experience. We've stayed there twice in the 2 BR suites and they usually come with a dining room and extra living room space. We just also stayed at the MGM Skylofts and for the money I think the MGM lofts might be a better value (if you can use that word for these kinds of accommodations).
Similar in theme to the normal rooms here, the suites have very modern looks and are made of high quality furnishings. The sky loft sections are nice since they have a separate check in area to beat the crowds, limo ride to/from the airport, and a lounge you can go to anytime you need a drink, cookie, cheese snack or to just get away from the crowds on the casino floor.
If you can spare the $ it's a nice way to enjoy a trip to LV. Your card will also double as a line pass at the aria buffet. BTW the aria buffet is a little pricy, but has really great food. It's annoying that you have to pay to be seated together if you are a group bigger than 4.
We also rented the cabana here and it's not a bad deal at around $400-600 depending on the day. It's a nice change of pace if you feel like relaxing by the pool versus gambling all day. You'll need to call to reserve ahead of time and then they confirm availability the morning of. The cabanas are more solid structures with misters, TV, sofa, and sink/fridge with some sodas and a cheese plate.
