I've tried this Sunday to take advantage of the one-day trip offer with the Shinkansen to go for some snowboarding. I took the cheapest plan I could find, which was for Yuzawa Park (10,800yen including the lift tickets) \r\n\r\nIt is said "what you pay is what you get". This could be applied for Yuzawa Park.
The courses were really short, the longest lift is just 550m. If you actually tried to speed up a bit you would run out of course
