Friendly reminder this Moon Landing Day that this website exists, where you can drop yourself at any point in the mission where the crew are awake and they'll probably be bantering with Houston.

The original Moon landing sites
"NASA contracted to have 15 flight-worthy Saturn V rockets produced. Apollo 11 achieved the first landing with the sixth Saturn V, leaving nine for follow-on landings. The following landing sites were chosen for these missions, planned to occur at intervals of approximately four months through July 1972."
Note: I've updated this list with the original tentative planned launch dates.
G-type Mission
Apollo 11: (G) Mare Tranquillitatis, July 1969
H-type missions
Apollo 12: (H1) Ocean of Storms (Surveyor 3 site), November 1969
Apollo 13: (H2) Fra Mauro Highlands, March 1970
Apollo 14: (H3) Littrow Crater, July 1970
Apollo 15: (H4) Censorinus Crater, November 1970
J-type missions, the extended stay missions
Apollo 16: (J1) Descartes Highlands or Tycho Crater (Surveyor 7 site), April 1971
Apollo 17: (J2) Marius Hills or Marius Hills volcanic domes, September 1971
Apollo 18: (J3) Copernicus crater or Schröter's Valley or Gassendi crater, February 1972, later July 1973
Apollo 19: (J4) Hadley Rille, July 1972, later December 1973
Apollo 20: (J5) Tycho Crater or Copernicus Crater or Marius Hills, December 1972, later July 1974
As we all know, plans were changed and missions were cancelled. But it's nice to see what was initially planned.
To compare with the actual landing sites and dates:
Apollo 12: (H1) Ocean of Storms (Surveyor 3 site), November 1969
Apollo 13: (H2) never landed, April 1970
Apollo 14: (H3) Fra Mauro, January-February 1971
Apollo 15: (J1) Hadley–Apennine, July-August 1971
Apollo 16: (J2) Descartes Highlands, April 1972
Apollo 17: (J3) Taurus–Littrow, December 1972
