I stayed here last weekend for one night on a Saturday and was familiar with the location as I frequent the Hard Rock Hotel and have also passed by the Hyatt Place on my way to the Vegas airport. Like almost all things in L.V., this is a much larger Hyatt Place than normal and it was pretty full from sports groups booked there (I think the S.D. State women's basketball team was one of the groups there). Seeing that, I was a bit nervous about room noise and the long lines for the complimentary breakfast but after requesting a quiet room, was surprised that it was a nice quiet corner room on the second floor. No noises from the other rooms around or above and the room was clean, well kept and comfortable (if you don't like firm beds then beware). As stated in some of the other posts, the only noise was from the airplanes overhead----having previously lived under a flight path, I think I was somewhat insulated from the noise but it is an issue to consider until they change the flight path.
The wait for the breakfast line was not too bad and while they had run out of a couple of things when I first got there, I was surprised at how quickly it was replenished (compared to some of the other Hyatt Places I've stayed at). Did not take advantage of the pool (which was outdoors and looked nice) or the exercise room (which was on the second floor). They have 2 internet stations by the breakfast area in addition to the free wi-fi throughout the hotel. Did not take advantage of the free airport shuttle as I had driven over (but this is a great feature for L.V.) nor the complimentary shuttle to Planet Hollywood as I was told you had to call for pickup. However, location across from the Hard Rock Hotel/Cafe is great and if you're a walker, a great selection of restaurants on their "Restaurant Row" on Flamingo Rd. is about 10 min walk away.
Overall, I was impressed with this hotel as I'm a frequent visitor to Vegas and I don't always stay or play on the Strip. If you're looking for Strip casinos or action or this is your first visit to L.V. you might want to pay extra for a strip casino. Otherwise, this is a great place to stay.
