Of the three days I was here in the colder part of Spring (yes it was still snowing and -11 degrees Celsius) there wasn't really much to do. A lot of the roads were either way covered in mounds of ice or black ice...something not too fun to drive over, and this place has a lot of windy, small roads The nearby lake was also frozen over...so yeah. I think for the most part we stayed inside except on the first and last day when we had to go towards Toronto.
Service is excellent though. When I was there it was one lady covering at the front desk and she was fluent in both French and English, great for us tourists haha. Dining was offered by a chef but my family brought and bought a lot of food already. They have a prix fixe menu as well as a la carte. Service is 24/7 also (room service included). Cool.
Definitely come by in warmer months and when the lake isn't frozen over. I'm sure there are a lot more things to do then. Although the snowflakes here were pretty; they were in actual snowflake formation, unlike the clumps you see elsewhere!
