^ I really should have thought to look at Memory Alpha in the first place!
Interesting to note that the expanded universe implies that other Galaxy Class ships might not have a 'Ten Forward' per se, 'The Return' even suggesting that another G-Class ship has a fourth shuttle bay on Deck Ten, Section One Forward.
On some level I like the idea that Galaxy Class ships are not all identical internally. Unlike earlier models, they're said to have been designed to be largely customisable. I think the Technical Manual
says something like 35% of the ship was left empty so that it could be changed as required.
