The best thing about Mardis Gras is location: short walk to the monorail station at Convention Centre, longer walk to the Sphere and the Strip (this walk is along the major road, so while sidewalk is there, not super pleasant). And, at least in our case - the price. Abundant parking unlike a lot of places nearby.
Not-so-good is their Wi-Fi.The property is dated, the room service is by request only.
We haven't tried it the food or drinks, but they offer breakfast, late night munches and drinks, which might be convenient to some. No kettle, coffee maker or microwave, fridge only.
