Stayed at this hotel for 6 nights mid-February when I was in town for a conference at Mandalay Bay. I initially chose this hotel for two reasons: it was completely non-smoking, and it was a cheaper rate than the conference hotels that my work would not pay for. :) I wasn't expecting a lot, but I was so pleasantly surprised!
The staff at this hotel was always really friendly and helpful. I was impressed that we were always greeted when we entered the lobby and we were always able to get help with our questions. The free shuttle to and from the Mandalay Bay conference center was awesome - it came every 1/2 hour and was a quick 10 minute ride over in the mornings. I typically took the shuttle to the conference center in the morning and walked back to the hotel in the evening - it is a 15-20 minute walk, and only slightly terrifying to cross the large intersections, although they all have lights and crosswalks.
The room was large and clean. I loved the free wifi (speed was great) and minifridge with microwave. The beds were very comfortable. My tall traveling partner was very excited that the shower heads were tall enough to avoid having to stoop in the shower. We were able to get a rollaway cot at no extra charge for a third roommate, although we were told that those are on a first come, first served basis.
I can't really comment on the food - there is a breakfast buffet (extra charge) and some dinner options as well, but we did not try them during our stay. The hotel is conveniently located to the strip and lots of dining options, and there is a Whole Foods a short drive or shuttle ride away.
I highly recommend this hotel is you are in town for a conference and want to stay convenient to the strip but not in a casino. It is quiet, clean, and the staff were fantastic.
