I hosted a week-long series of meetings for over 200 attendees. The service was beyond impeccable - I heard numerous compliments for both large and small ways the staff made us comfortable. I worked with dozens of staff people, and they were uniformly helpful and cheerful - not once did I hear "no we can't do that". Additionally, the food from banquet services was far better than other hotels I've used.
As an example, on Wednesday afternoon I asked if we could have Thursday lunch on the lawn instead of the dining room, since the daytime temperature was nice. Not only did they make the switch without a complaint, but no additional charge (unlike other hotels), and they even gave me an opportunity an hour before to change my mind back when the wind kicked up.
One member of my group forgot the charger for his laptop. He went to the concierge desk which lent him a replacement (free!) that fit his model - most hotels wouldn't have had a stock, and even if they did would have charged for it. That made a big impression!
Location is very nice, on the lake, with great hiking and biking trails just outside the door. (And the hotel rents bikes, which are in good condition.) It's just a few blocks walk to the music and dining areas.
Yes, it's not quite as luxurious as other Four Seasons hotels. But having the outstanding service was far more important than a huge hotel room.
