Dear reader, I bought them.
I've gone for the cheapest category (North Stand) and grandparents have kindly agreed to give the boys' tickets as presents, so not too much of an outlay.
Somewhat counter to the general tone of this thread, my sons and I have been Albion+ members for the last few seasons and attended a handful of games per season, but am now considering getting half-season tickets if they become available - the ones for my sons would be Christmas presents.
