Round Robin XVIII - Tour Party by Arcadia

Quadrants start in the NW corner and move clockwise round the grid, with the direction of answers moving similarly, so Quadrant A's answers are across and down, Quadrant B's down and back, and so on.  Clues for each quadrant are in alphabetical order of their six-letter answers, which must be entered where they will fit; as must the four 12-letter entries, which pay tribute to a cruciverbalist scholar (three words) who generally eschews cartes blanches (two words). Solvers should show up (three words) congratulations on his achievements (three words). Chambers (2016) is the main reference. One entry is in Collins.
