From Toya Train Station Bus Stop (immediately visible when you exit the Train Station), you can take a bus/taxi. I chose the cheaper option which costs about Y340. It's about 7 stops to Toyako Onsen Bus Terminal (serving as a transport node at Toyako Onsen) and another 3 stops to Motomachi Bus Stop (2 minutes walk to Hotel Hanabi). Travelling time by bus is about 20-25 min, but subject to waiting time (take note of the bus service timings). Google Maps works well to provide suggested travelling route and timings.
I booked a single room for one night that was clean and served it's purpose. It felt a lot like a hostel than a hotel but has an onsen. My booking included a buffet dinner and breakfast which was critical as there weren't many food options around the area. Both buffet had a wide selection to cater to Asian/Western food preferences. There's a 7-Eleven that is about 5-10 min walk away.
There's a Tourist Information Centre at the Bus Terminal. The Bus Terminal is also reachable by walking which will take about 15-20 min.
Hotel Hanabi is one of many lodging options along Lake Toya, and just walking outside the hotel, I was already able to capture the nice photo of Mount Yotei.
During the time I was there (mid-end Apr), there were no bus options so the only way to travel to Usuzan Ropeway was by taxi booking done at the hotel reception.
It costed about Y1900 one-way and took about 15-20 min. Once I was done visiting, another taxi booking is done at the Usuzan Ropeway counter to the next destination.
