You make a good point in saying that if we stay on the slope we will be less likely to try other places.
I think we are looking at the Prince Hirufutei hotel in Niseko, it seems to be the place we wanted to from both of our research we have decided that we most wanted to go to (without the other knowing what we were doing)
Will the lifts at Niseko (39 or so?) last a week or even 2 weeks of riding or would you expect we'd want to explore other options by then.
Ride it like you stole it.
