Dear Hiro San,

Konichiwa! My family had a great time in Hoshino! Everything is perfect except we were not able to book skiing lesson. Nevertheless, we managed to have a beginner course and had a lot of fun in other activities.
We plan to return to Hoshino resort the next Christmas and this time we will make the skiing lesson reservation very much in advance.
Thank you for your thoroughness in arranging everything for our holiday! We’ll need your help this year for Hoshino!

Happy new year!
Best regards,
