We went with 2 other families. Found the rooms to be good for the families. Split everyone up into the 3 rooms, although one set of kids went to sleep in the loft. It has a ladder, so it may not be suitable for those who want to climb down in the dark. May sure that you take care of "business" before going to bed.
No cell service at the house (ATT) although you can get on the wi fi and use your iphone to send a text message or email. The reception on the mountain was spotty as well, so we went to the old school, "meet you at 2 PM on the deck of the St. Bernard for drinks" method. Worked well for us!
Approximately 1.8 miles to parking lots, so it is probably too far to walk to the lifts, so we drove the short distance.
The kids could play outside on the impromptu sledding trails, so bring a sled or a cafeteria tray. This was probably the best thing about it. You could let the kids go outside and play and not have to worry about traffic or losing them to the Abominable Snowman. It really helped with the noise and traffic inside the house.
Kitchen and dining room are a big plus! Made meals "Family style" when we didn't go the the St. Bernard for their "Family Style" meals. Go figure! Rent the adjoining house, and all the rooms at "Cottam's Cottage" and you will have a great time!
