I stayed at the hotel “Resort Kumano Club”
http://www.resortkumanoclub.com/
I made a reservation with Booking.com.
One night stay including breakfast.
The room sleeps four.
It was 8,300 yen per person.
This hotel was nice.
The room was wide and clean.
Breakfast was very delicious and healthy.
The hot spring was good.
They can pick you up from JR Kumano-shi Station.
If you need to be picked up, you have to say it when you make a reservation.
