Have a nice trip to Hokusai in Obuse,Snow Monkey and to Japanese Onsen "Yukku-land"(It is the tour of 2 days and 1 night at the Robin.)The minimum amount of running staff is 3,so the charge is a total of 3 persons and this is a plan only for weekdays.
The room is Western style room with 3 single beds and one extra bed but it is very small room, not a room with bath.
Why don't you extend your staying days in Robin?
I recommend you that staying further in at least two days or more to enjoy skiing (website hidden) that case please book other types of Robin's room.
Robin is in the Minenohara Skiing resort.
I'll take you to Karuizawa on the last day that you planned.
It is the time when you can take a bath for the Robin from 4:00 p.m. until 10:30 p.m.
