There are some neat places to check out in the area as well, including Chureito Pagoda, Oshino Hakkai and Iyashi no Sato. If you're not really down for anything more than "light" skiing/boarding, then Niseko in Winter probably isn't going to be as appealing of a place. The tables are turned if you happen to be visiting between Feb. 4-11, which are the 2024 dates for the Sapporo Snow Festival, which is a wonderful exhibition and definitely worth visiting. Then, you can combine Sapporo with Niseko, with a stop at charming Otaru town along the way.

Zaborin is going to be a bit more expensive than Fufu Kawaguchiko, although the base rooms at the former are slightly more spacious. You'll want at least a Precious Suite room at Fufu, but even then, it's a bit tighter in space but quite a bit cheaper.

For Fuji Five Lakes, one option would be to combine it with Hakone or Izu. A Fufu + Asaba combo (save Asaba for the end) would be pretty awesome combo.
