I booked a very reasonable fare ($656 RT in June) for myself and other family members (3 adults, 4 older teenagers, and a lap infant) IAD-SVO-CDG. The connection has a 6 hour layover which is fine given the number in our group. Will we need a VISA, sounds like not based on other posts? Any concerns we need to consider with connecting? What is the waiting like as far as comfort and charging stations for an infant?
