Will be visiting with family with a small kid. We primarily want to enjoy the beauty of Mt. Kanchendzonga and any other places worth a must visit. Not really looking to cover all good places, just the best ones. We are thinking of 4-5 days for Darjeeling and any one more place which we are not so sure of. Looking for opinion as what would be the other best place to be and what can be a best itinerary? Shall we pre-book any car for the trip?
