I often agree with mayodave, but in this case I think the OP has a point. It's not only the toilet itself. It's also a question of foot traffic through the cabin to get to the toilet. So whether CX is willing to block off that toilet on the 77H for PEY pax will go to what kind of an experience they hope to create with that product. Since the smaller, quieter, more exclusive cabin is part of the marketing pitch, this is a potential problem.
