Realistically very difficult for international visitors. US citizens apply via Congress member; international visitors apply via their own embassy 6+ months ahead.

Exterior photo + Hay-Adams brunch combo is the realistic Korean-visitor canon.

Cherry blossoms peak late March-early April (peak bloom only 4-7 days, exact dates impossible to predict 2+ weeks ahead). 3,750 Yoshino cherry trees gifted by Japan in 1912 ring the Tidal Basin (1-mile walking loop).
