Yes — five of them, which Hamad International Airport calls activity nodes, spread across the terminal: one in Concourse A, one in Concourse B, and three in Concourse C. Each combines televisions, internet browsing, toys, mini-rides and climbing frames, and the airport describes them as designed for children of all ages, positioned near retail and food and beverage outlets so parents can stay put while children play. No gate numbers are published for any of the five, so the airport's own instruction is to follow the signage, ask at an information desk, or check the airport map once you're in the terminal. All five sit past security, since DOH funnels arriving, transferring and departing passengers through the same integrated terminal building.
