Dear Mr. Dwee E., Thank you for your feedback and suggestions regarding the blankets being too thin. We will look into this, but if you prefer, you can try other blankets that better suit your travel needs in Wonosobo. Regarding ventilation, we will reconsider this, as you may be able to request additional blankets if you feel cold. The hotel apologizes for your inconvenience and sincerely hopes to welcome you and your family back on your next visit to Wonosobo. Sincerely, General Manager, Dyeong Hotel
