Spoilers A Knight of the Seven Kingdoms

I do have one potential quibble: they comment that Aemon was training to be a maester. But I thought that that decision came later, closer to when he turned down the crown.

Nope, he was sent to the Citadel at a fairly young age and in the books is already training to earn his Maester's chain when Egg and Dunk visit him.

Clint is correct. You may be thinking about Aemon's decision to join the Night's Watch, which did come later, and he did it to remove himself from contention for the Iron Throne.
