We loved our stay in Big Sky. The condo is very well located. The shuttle (which comes frequently) is across the street from the back entrance. The incline is steep, but you can choose instead to exit the front entrance and walk around. The fact that the shuttle stop is the second one ensures that you will always have a seat.
Skiing in on the way back was a little tricky at first, as we kept missing the turn-offs. But once we got the hang of it, it worked really well, with not too much poling involved.
The condo itself with extremely well stocked, from supplies to kitchenware. The 2BR/2BA with W/D worked perfectly for our family. The outdoor hot tub right outside the slider door was awesome to slip into after a day on the slopes.
The host/property manager was extremely flexible and prompt with communication. Everything worked out extremely well. If we had to complain .... as the unit is on the first floor, and if you're unlucky to have a young boisterous family above you, you'll need a white noise maker (which we happened to have!).
Again, we really loved our stay at Big Sky. The beautiful backdrop, wide and often empty trails and friendly vibe are all unbeatable!
