Stayed at the MLI from 12/28 - 1/2, with my wife and 2 kids, (12 and 15). We stayed in the mountainview building, ausable suite, and had enough room for all. Kids shared a queen pull-out, and my wife and I enjoyed the King bed. It was a non-ski vacation because of an injury, but we were out and about all the time.
The room itself has an older, ski-lodge type feel to it appropriate to the surroundings...clean, comfortable if not a little rustic in feel, still very comfortable and pretty. We looked out onto the lake and really enjoyed the view. It was truly beautiful as it snowed on and off almost the whole time we were there!
We enjoyed breakfast at the hotel twice... it was good, but not exceptional. We enjoyed the food, at The Breakfast Club in town, more. Had dinner at the hotel two times, including their New Year's Eve seating. Again, it was good, but not exceptional. We made our way into town on the other nights for dinner.
The hotel was beautifully decorated and coupled with the snow was really quite gorgeous.
The gym was serviceable and clean. The spa was very nice with a beautiful locker room and hot tub, the massage itself was enjoyed.
The hotel does itself proud on all counts and only loses one "star" because it was a little less than I expected based on the fees. In all fairness, I think being there during a Holiday week might have caused them to be just a tiny bit off their game, and being sensitive to customer service, I felt it more than most. Overall the hotel is beautiful, well-serviced and most of the employees are a pleasure!
I'd recommend this hotel to anyone looking to enjoy Lake Placid.
