Have you found out anything about this yet? If not, I have a picture of that side that shows your cabin and the window washing equipment. We have been on the Millennium two times. There is window washing equipment, but it can be moved anywhere along the balcony area. It is usually stored at the front for the forward cabins and at the rear for the aft cabins. My picture shows it in those locations.
My travel agent assures me that there is no obstruction,should I believe him? Could you email me your pictures? My email address is firstname.lastname@example.org. I would really appreciate it. Thanks in advance.
