The worst experience ever. I waited at a stop for over an hour when I was told that a bus would be available every 30 minutes. The other Bus company Big Bus B came by six times before Chicago Double Decker even came once. This is very inconsistent and inconvenient. DO NOT USE CHICAGO DOUBLE DECKER IF YOU NEED SOMETHING CONSISTENT AND RELIABLE. Save yourself some stress and use Big Bus B. They are the REAL DEAL.
