Stayed here in early Aug 2023. It was a very pleasant experience, or rather the best throughout my stay in Hokkaido.
Booked a club room and play area was just right outside the room, perfect for my 2.5yo boy. He loved it so much that he was asking for hotel playground even when we had moved on to other hotel.
Room is huge, view is good, bed is comfy.
Hotel breakfast and dinner were great, but not exceptional. It would be great to have more varieties during breakfast time.
