VS075 MAN - MCO Seating!

Hello everyone.
First post on the forum so please go easy on me! This site is fantastic and full of brilliant information.
Me and my wife are flying to Orlando with Virgin on July 14th. Can't wait. We are going with my brother and his wife and their 2 kids.
Now seat choice wise I had asked for me & my wife to go in 62 H&K the 2 seaters that are at the rear and my brother and his family to go in 62 DEFG.
However my brother has been assigned his seats ok, but me and my wife have been moved to 61 H&K.
I assume the reason for this is because on SOME VS aircraft seats 62 H&K have the extra legroom where you pay £30 at Check In. Now I don't mind paying the extra but I know only G-VTOP, G-VAST & G-VXLG have the extra leg room seats in rows 62 & 63. Obviously I won't know which aircraft I am on until the day, so want to know if seats 61 H&K are ok if they don't have the extra legroom? Looked at Seat Maps on here but not many comments.
Also I hear some VS aircraft don't have a window in seats 61H&K (Hotlips being 1) but does anyone know which other aircraft don't have a window at these seats???? What's the reason for no windows?
Hope you can help me!
