61 does have windows, but you will see they are not that well aligned to the seat, one window a bit to far foward and one which will need you to twist your neck, it's more behind you. Whereas 62 and 64 have much better alignment.

Leg room in WTP is pretty good throughout, and particularly so on the A380, even WT isn't that squashed in.
