I've been to Vegas dozens of times, but this was my first stay at Mandalay Bay. It's a bit off the beaten path, but not too far. Quick cab ride to the main strip.
I found the room to be modern, clean and comfortable. However, it was very cold when I was there and the heater didn't do a great job. I maxxed it out but it couldn't keep the room warm. Bit disappointing.
The pool area looked to be quite nice, but was closed for December. I'd be interested in coming back during the warmer months to give it a try.
The food selection was OK at the property.
Overall, the property is an A-OK stay.
3 stars!
