First Family Trip Across Three Generations
This was our second stay at Koga no I Resort and our first trip with three generations together. From the phone support before arrival to the warm welcome, front desk service, and dining staff, every interaction was exceptional. We had specific requests such as arranging three rooms side by side and setting up a Hollywood twin bed due to having infants in our group. These were perfectly accommodated, and they even provided a diaper disposal bin upon noticing we had a baby with us—truly thoughtful service. The dinner and breakfast offered a wide variety of delicious options. The freshly prepared dishes like meat, tempura, sushi, and rice balls were especially delightful. However, despite the large number of tables available, the food area felt slightly cramped at times with frequent lines forming. The public bath had just the right water temperature. The open-air bath without a roof provided an incredible sense of openness; bathing with my grandchild while feeling the breeze was an unforgettable experience—we could have stayed there forever (playing). It was my first Saturday stay in decades, so I was surprised by how crowded it was. However, thanks to the excellent management by staff at both reception and dining areas, we never felt uncomfortable throughout our stay.

The buffet and onsen...
The buffet and onsen were very satisfying. All the staff were kind, allowing us to have a pleasant stay. I would like to stay again. Thank you very much!
