I have stayed at other Fairfield Inns and decided to give the Fairfield Inn South a try when I was in Vegas for a long weekend.
I am sorry to say that I don't plan on staying here again and this is why:

Being the end of September, it was still in the high 90s during the day and the high 70s/low 80s at night. This meant that I needed the air conditioning on in my room. The problem is, either you are in the North Pole or the Sahara Desert - no in between. The HVAC unit on the floor is right next to the bed.
Not only it is very noisy when it is on, there are no dials on the unit for high cool/low cool, high fan/low fan or whatever.
All there is is a thermostat unit on the wall. The thermostat has a button for on or auto, and one for heat/cool/off. No high/low fan button. And you can adjust the temperature with the little up/down arrows. Here lies the problem -
because you can't put the fan on high or low the unit only has 1 function - blow freezing cold Arctic air out at a high rate and when the room cools to the temperature on the thermostat, it shuts off. No low fan to run. Therefore you are either freezing or boiling in the room. No in between. I got very little sleep the 2 nights I was there because I was up constantly all night adjusting the thermostat. It was terrible!! I would never stay at this hotel again unless they add a high/low button to the thermostat.

Other than the HVAC problem and the fact that the bed was right next to the unit (maybe 2 feet from it!) , the hotel was fine. The room was very small but they managed to have a big desk with plenty of room on it and a little armchair & footstool. Small closet. The king size bed was fabulous as were the wonderful feather pillows. The staff were all very nice and the breakfast was good. There was plenty of hot water and good water pressure.

I did not have a suite, I just had a standard room. I did not hear any planes overhead (yes, the hotel is fairly close to the airport runways but so are the Mandalay Bay & many other strip hotels!)
perhaps because the noisy HVAC unitl drowned them out! and I did not notice any smell in the hallways.

Had a fantastic last minute booking/stay at this Fairfield just south of the LV strip, and got a great price for my last minute effort. Extremely friendly staff, extremely comfortable bedding, and a great breakfast. We wouldn't hesitate to stay here if we ever went back. It was in a great location if you wanted to be close to the strip but not right on the strip. Fantastic facility!

We stayed at the resort on the 7th Jan. and just loved the place. Everything was so professional from the front desk to the quality of the room. Our room was a twin suite in the main building. I have stayed in hotels all over the world from very basic to very comfortable and would rate this resort very highly . Our twin suite had two bathrooms one with a jacuzie. Three bedrooms two fully fitted kitchens four tellys all rooms were fitted with upmarket furntiure and fittings. In the centre of the resort were two very safe swimming pools and two heated jacuzies. Deck chairs, loungers and palm trees completed this area. At night this place was lit up which looked impressive. If you could improve this place I would reccomend a second shuttle bus the Aladin hotel is the nearest hotel on the strip but is still 10 mins walk away and late at night this could be awkward as the other shuttle bus is at the other end of the stip so if you are in the Luxor you are left with little options but to walk or get a cab which with tips and all could set you back 20 dollars a trip. Also the shop could be a bit better stocked. I know these are minors details but would be a big improvement to the quality of our stay. Overall I would highly reccomend this place.

The Fairfield Inn is located on a off the beaten path area of Las Vegas. This would be ok if it wasn't near where the planes take-off and land.

The staff is terrific. My luggage did not arrive with the plane. I was dressed in a long sleeve shirt, and had no toiletries. The front desk person hooked me up with two Marriott T-shirt's, and a ton of supplies such as lotion, razor, toothbrush, toothpaste, etc.

The hallways did smell funny and did not look very posh. The room itself was very nice. It was extremely clean, and did not smell at all. There is a Microwave, fridge, separate living room with a large TV, a huge bedroom with another TV, and a large bathroom with a strong water pressure shower. The bed was so comfortable I wanted to take it home.

There is a huge negative to this hotel. It is very close to where the planes take-off and land. Unless you enjoy being woken up at 7:00am by the sound of jet engines, I would avoid this hotel.
