Also, you might not need to be right by the window to get a decent view of the fireworks. I was not right by the window in February, but the first table on the other side of the aisle, about 4 table rows from the window and I had as good a view as the people at the window. That said, it still just an okay view of the fireworks as there is quite a distance.
We did not even book the reservations for the view, it just happened to coincide with our reservation.
