I have been to Sandy Lane numerous times over the last 15 years. My girlfriends and I use it as a winter weekend retreat, and allow ourselves to be kids again. We have stayed in the cabins, chalets and the alpine and all are clean, welcoming and set up for minimum house duties. The toboggan hill is amazing, the ice rinks are well maintained and there are ski trails not too far away. Since the majority of the visitors are people on snowmobiles, there are no lines, no crowds and no worries about embarrassing ourselves. The owners are great, easy to deal with and very welcoming. I've read that some people complain that the cabins are dated and could use a makeover, but to me, thats part of the charm.
I recommend this place to anyone looking for a nice getaway. So far I've only been there in the winter, but I can only imagine the fun I would have there in the summer!
