In September, 15th is Saturday, 16th Sunday, 17th Respect-for-the Aged Day, a holiday.
So we are planning to go to Izu Peninsula.
On the 15th, a reservation has been made at Hotel Ito Powell. I am waiting for a cancellation at GRAND XIV Hatsushima Club. However, it is not very probable.
Probably, I should give up and stay for two nights in Hotel Ito Powell.
