When i was in calis, we booked through cafe pazaar, and were picked up there. Only problem was that the bus did not return while 5 o clock. So, as it was too long for the kids, they gave us a lift up to the top road where the dolmus runs, as it does not go the mile and a half from the main road to the park. Alternately you could book in calis and they will pick you up from your hotel.
