VS changed my seats!

Hi All,
I'm booked on a MCO to BFS flight next May. On logging on, by chance, I noticed our 3 seats were no longer in a row (had originally PE - two by the window, then adjoining aisle of middle block), now its two by the window and one in the row behind.
We are travelling with a 4 yr old, and our intention was to have her by the window, then taking turns in the seat next to her, to keep her amused and entertained.

Upon contacting VA, it's because the aircraft has changed from a 747 to A330, but looking at the seat map now, practically every seat is filled on the aircraft!! I find this hard to believe on a flight so far away, and off-peak!

All they could suggest I do was keep an eye on it, and hope that a seat frees up.

Any other suggestions would be welcomed!
Thanks, Steve

I would assume the full seat map is a side effect of the aircraft change. I would just keep an eye on it every now and then and it will correct itself. Don't sweat over it, your flight is still seven months away.

Thanks Slimpy Jones - Frustrating, and not the end of the world if it doesnt sort itself, but frustrating none the less! Hoping it'll be a newly refitted A330!

By then it certainly should be!
