For my second time visit at Tateyama, we want to have a better preparation. So we stay one night at next to the station - Green View Tateyama.
It is a nice hotel and reasonable price. Below US$100 per adult, it includes a great dinner, breakfast and hot spring.
I had been to St. Moritz before. This hotel decoration is very similar, it is full of Swiss style. And people may see the snow just going up to the mountaint.
Travelling tips: I drive by car for both visit, but it is very dangerous when it is misty and dark. If possible, please visit there by train
