The Ritz Carlton, located at the middle of Northstar Ski Resort is a great place to stay. They continually run specials that make it more affordable to stay at this luxury resort.
Everyone was very friendly and we first thought it would be a little "stuffy" but happily the people working plus the guests were very friendly.
The service was great from the ski valet (complimentary) to the stores and restaurants. The rooms were very comfortable with large bathrooms which made it nice coming back from a day of skiing. They have a outdoor pool which is heated to 94 degrees and stays open year round, a large fitness center and a spa which my wife said was excellent.
The food was a little expensive and there is a resort fee of $25 per day but overall it was worth it.
