A quick Atlantis related Question

Can anyone remember how you get out onto the balcony?? I can't remember if it's changed or not since season 1 (my single lonely DVD being s1 and all of s2 and s3 being on the working but not accessible external hard drive)

I ask due to a certain part of the fic I'm working on at the moment has two of the guys on the balcony and I was trying to work out how they get out there....and from what was seen on 'Pegasus Project' you don't take an easily visible route out there...

any help would be much appreciated!

thanks x
