I stayed here for a business conference and thought they did a nice job. They dressed up the decor a bit from my stays in prior years. It sort of looks like a mini-"W" with the mood lighting and modern features. You'll basically find the same consistent Marriott amenities though I will say their Conceirge lounge served above average food. They had nice beef and potatoes one night for dinner and their breakfast always features a big bowl of fresh berries rather than the tired melon and pineapple you often find at hotels. They also have a full service restaurant on-site and it was great. Everyone at my table thoroughly enjoyed their food and I thought the family style side dishes was nice. All was very good and the service was excellent. I would eat there again. When you're in Vegas for business its nice to avoid the hub-bub of the strip and keep it simple. I particularly enjoyed not having to get out in traffic for dinner.
For those of you travelling here for gambling and everything on the strip, this hotel will serve you just fine, but it is a bit outside the action. You are close to the strip, but that probably isn't close enough. You really don't feel like you are in Vegas so I would recommend one of the big strip hotels for a true Vegas experience. Might be great for those who want accessible Vegas but like to get away from it also.
Last word, this is a very clean hotel. Relatively new or at least feels that way.
