We visit Boyne Highlands every year between Christmas and New Years. The staff in all regards (lift operators, wait staff, housekeeping, etc) is very nice and friendly. The food quality is great at all the restaurant properties. This was probably the best skiing ever at this time of year!
We stayed at the Bartley House which is the lower cost on property lodging. It's considered a ski in but short walk up a hill to the lift. It's a bit of a walk to get breakfast (which is in the main lodge) but no big deal.
My major complaint is the Bartley house rooms are due for an upgrade. The bathrooms are old and the rooms are basic. The TV is "old school" but setup for a wide screen and thus all the programming is chopped off (couldn't see the scores of the football games). For not a lot of money they can get some new TVs, upgrade the bathrooms, decor etc and get a lot of perceived value. (the beds are comfortable though)
The WiFi still needs to improvement.
