I just returned from staying at this hotel and continue to think this is the best hotel in all of Las Vegas. I stay here several times a year and love the fact that there is no casino, no smoking and the rooms are in fabulous condition, not to mention the service is awesome and genuine (unlike gaming hotels). If you are looking for a comfortable, quiet and safe hotel, this is it. I dislike the "big box" hotels because they are difficult to navigate, stink of smoke, are noisy (especially when the drunks return to their rooms at 3am) and are far too expensive. This is the best hotel!

Stayed here for the convenience to the Las Vegas Convention Center. Easy trip from the airport (about 15 min). Liked the layout of the room, very spacious. Pool is very small, but clean. Rooms were spotless. Beds are the best (love Mariott beds). Right across the street from the monorail. Easy to get anywhere in Las Vegas. Internet was too expensive, so I used the business center, 3 computers, printers, and very secluded for conducting business. All in all a good stay.

We stayed at the Marriott for 2 nights and were extremely satisfied. We got a deal for 87 USD per night (including parking but not breakfast). The room was absolutely superb, very large with a separate sitting room, 2 TVs, very big bathroom and very comfortable bed. The staff was very friendly and accomodating. The hotel is located next to the LV convention center, close to the Strip (about 5-10 minutes walk) but far enough from the noise and lights (which was great for us!). Breakfast is somewhat pricy (around 20 USD per person), but offers a good variety of food/drinks. We'd certainly recommend this hotel for anyone wanting to stay close to but not on the Strip.

I stayed from May 28th through June 2nd, I visited Las Vegas for business, I wanted to stay away from the strip, I didn't want to be bothered with the crows nor the gambling, I was able to find it in this hotel, the room are spacious, very clean, staff was very courteous as well.
If the above mentioned is what you are looking for this is the place for you, since the hotel is a little away from the strip, he rates are great.
