Just returned from a trip to Keystone Lodge. The property is great! As a family, we were impressed by the great extras like the beautiful lakeside skating rink, ice sculptures, and chocolate village. Our room was very quiet, quite large, and the service was excellent. Free valet service right at the door for your car and the bus service made everything so much easier.
Pool area is nice- we were glad to use it, yet I thought they should have kept the pools and the spa separate. Combining the two leads to a strange mashing of kids playing and spa people. Hot Tubs are a little small- could probably add one or two. Pool is heated and is "indoor/outdoor" (although it's 99% outside, with an indoor entry area only). Humidifier was provided in our room, which we thought was a nice offering in the dry climate. Design is a little 70s/80s but they have done a good job updating the decor and keeping the place looking new and clean.
We would definitely return.
