Here goes my experience for Mumbai consulate.
It was on 20th Feb 3:30 PM. For me I had to carry a photograph additionally for my 9 months daughter. Make sure photo is recently taken. They asked one person to get latest photograph and come back as he mentioned the photograph is 6 months older.
You need to carry (or at least keep handy) only DS-160 Confirmation Form and all the passports along with appointment confirmation letter for each applicant. It took around half an hour for finger printing.
It was on 21st Feb 10:30 AM. Reached there around 10:00 with my wife and daughter. There was a queue but they allowed us to enter directly because of child :). After finger print verification they directly called for the interview in 5-10 minutes as there were few people only in our queue.

If you are planning to book a hotel nearby BKC Mumbai to stay overnight, please spend some time reading hotel reviews (Especially with poor, terrible ratings) online and make sure you are getting what you expect. Most of the hotels in this area are not good for the money.
Be cool and confident and everything will follow.
