I think you are correct on retaining seats for next year.I am pretty sure the $250 allowed me to select seats which will be honored next season.
I guess the big question would be why not hold off virtual seating until this upcoming season?
I also believe we get a tax deduction and RAF points for each $250 seat donation.
It would be nice (as well as proper and prudent) to award some additional permanent RAF points to people that gave this year. This was a hardship on everyone that donated.
