Read through all 130 pages of this thread as I have a booking for LGW-MCO and wanted advice for a good seat. I have selected 4K on what appears to be a 32J version, either a 77S or 77T. I couldn't find much info on the access to the seat but I have come accross a video showing a reasonable amount of 4A whch I believe is a mirror image of 4K. It also shows a good view of the window arrangement i.e. the missing window.
I think the link will take you to the relevant part of the video but it is at 21:02 if not
