Spent 4 nights in lovely unit in Red Hawk Lodge a short 2 minute walk from main Gondola from 18-21 Dec13.
This is a great family ski destination with excellent groomed trails on most slopes and some challenging black runs on the back mountain. As per another recent review we loved the long runs, particularly the main 'Schoolmarm' down the front on the mountain for my teenagers who were learning, plus the long blue runs in 'Outback' in the two uncrowded mountains to the rear. It was very cold but still enjoyable as you could catch the Gondola to the top to get warm again. The staff all over the mountain were very friendly and the food at the restaurants of a high standard. Hot chocolate was a favourite!
Only negatives were the high prices and the 20% 'resort' tax on any items in the area on the Keystone side of the main road. Luckily we hired from a great shop at 'Mountain View Plaza' and by chance saved the 20% tax as we were across the road from the resort boundary. Also didn't like the $109 day ticket, which was $104 when we arrived but they arbitrarily put it up on our third day.
Other disappointment was our private lesson for three of us in our family. The instructor was very friendly but gave very little concrete coaching all day. It was just the occasional comment then 'follow me' so at the end of the day we felt like we were not much further ahead than when we started and it was a waste of $679 for our family. My teenage girls were put off by this particularly. I am sure this is just pot luck as other instructors would be better, but a big disappointment for us.
Overall Keystone is a lovely place to ski with great shuttle buses running regularly for free and great skiing, particularly long runs for greens and blues. We will be back although it is a long way from Australia!
