I have been skiing at Mt St Louis Moonstone for the past years along with many other ski resorts in Ontario. In the past two years I have decided to purchase the night season pass. This year has been the worst, the team at Mt St Louis Moonstone is not grooming ever the trails after 3 PM, the trail condition is worse and the ride quality has been degrading at a constant pace during the years, with moguls and accumulated snow. I have been trying to talk with the people at the lifts at no avail. Even the entrance at the lift the snow/ice is accumulating making it difficult to enter and load the chair. I have been at other resorts and the teams there are working around the clock in making sure the access at the lifts and the trail condition is top notch even at the evening hours. More than that even if for the same price for the night season pass the other resorts are offering 7 nights, instead of 5, for night skiing. It seems that the afflux of new members coming from the more expensive places are making the team at Mt St Louis Moonstone is unable or unwilling to keep the quality standards we were so much used to. Unfortunately, the quality is degrading at Mt St Louis Moonstone and is pushing me away to other resorts for the next season.
