Personally I managed to get last twin room! Got new rainbow plaza and indeed travelled from shinjuku to hakone yamato station - it is nearest hotel in vincity and tge largest! It is next nice river and we took lift to level 2. I like thank the ever smiling "zhong shan" customer service officer. She brought me to my room to checkin and ensure i am totally satisfy with the room. I asked early check in as need rush to lake aiki via my hakone free pass. High point is the superb public bath - my main purpose of booking n to relax after exploring hakone vincinity
I loved this place, but I also was ready to go after 36 hours. It has charm, it has great service, and it is in a beautiful setting. The big building in the back is late 60s hotel, and it does not feel like it's seen many updates. By volume, most people will stay here. Overall, this seems to be like the place you would go with your grandparents when you want to take them somewhere nice.
