I am sharing my experience with reference to ramoji film city. We may have this as a one day trip. It is in 2000 acres. It is a preplanned and built into different portions.
I really had a great experience here with my family. It has a bird parks butterfly parks. As it is spreaded in large I recommend to spend one day full.
Totally it is well organised and staff are very helpful. I recommend all to visit this place.
