Presidential: $750 - $1000

Now I dunno. A Bellagio penthouse for Thursday night will run $950. The smallest SkyLofts at MGM Grand can be had for $800 next Thursday night. (They were full-up this week.) Given the amenities and elegance of each of those, not to mention the total packages that are those resorts, I think the Sahara's prices here seem a bit steep.
