I had to give explanations to Ghanshyam bhai, owner of the hotel Annapoorna in Sasan Gir.
I requested him on phone, to book a room for 27th and 28th December night. During our conversation he told me that December end is a peak tourist season. Since only a limited number of vehicles are allowed inside the jungle for three safari slots of 6:30 am-9:30 am, 12:30pm–3:30 pm and 3:30pm -6:30 pm, he advised me to book the safari in advance. For this he suggested to fax an application along with identity proof, to the forest office, with his name on top of that application so that he could collect the permit on my behalf.
