VS065 Extra legroom seats

We are flying on 24th Oct to Jamaica on VS065.
We usually upgrade to PE but this cabin is full.
We live 15 mins from Gatwick, so will be doing twilight check in but not until 4pm (when the kids come out of school)
Do you think all the extra legroom seats will go in those 3 hours.
Not sure how many there are and how popular.
Will also take a look at online check in just in case the 2 x 2 seats at the rear of the aircraft are available.
Any thoughts on the extra legroom seats, the kids are under 16, so the exit rows are out.
Many thanks

I had a look and sit in one of the extra leg room seats when we went to MCO in Feb and the a/c was empty (only 60 pax on the whole a/c). Looking at them it doesn't look that much difference but when you sit down it is quite noticeable.

Will they go? An impossible question to answer, it just depends if other pax who check in before you want them or not. I think you will find most of the 2 seats at the back of the a/c are now extra leg room seats. I'm not sure on the exact number, but it does vary from a/c to a/c.
