I feel one of the main advantages to cruising at the old Babylon was the layout. The new Babylon is mostly linear dead-ends, i.e. you walk down a corridor, then you have to walk back. The old Babylon was like a giant loop, with some nice lounge areas for rest stops along the way. You could keep walking around without ever having to backtrack. This does wonders for psychology IMHO. Oh, and the old shower in the back with the sunroof (light!) is something else I miss.
