Where can I stay in Gero Onsen where I can enjoy the night view and all-you-can-eat meals?

I'm thinking of going on an overnight trip with my girlfriend to Gero Onsen, which is known for its skin-beautifying properties. I'm looking for a place to stay where I can enjoy the night view so that she'll be happy. We both love to eat, so I'd like to have an all-you-can-eat buffet.

I want to use the "Yumeguri-Tegata (the bathing ticket which can use for other hot spring facility)" to go on a hot spring tour of Gero Onsen! Are there any hot spring inns that are popular based on reviews?

After visiting Takayama, I plan to go to Gero Onsen. I would like to visit the hot springs, but are there any recommended accommodations that are eligible for the "Yumeguri-Tegata (the bathing ticket which can use for other hot spring facility)"? Since I will be staying for two nights, I would like to keep the accommodation cost low, under 15,000 yen per night. I will arrive at Gero Onsen in the evening of the first night and stay there for two nights. I would like to visit the hot springs while sightseeing, and visit at least two more hot springs in addition to the accommodation I will be staying at.
