Long Island Lodging: Best place to stay hands down is the "1708 House". I stayed there for 8 or 9 days a few years back. You are missing Friar's Head on Long Island, that will give you your Coore and Crenshaw course and a short ferry ridge from Long Isand is Fisher's Island, that will give you at Seth Raynor.
Missing also from your itinerary is a Mike Strantz course, the best being Tobacco Road in Pinehurst, and if you do that, you could do Pinehurst #2, a premier Donald Ross Course.
If you do Colo, you want to do a Jim Engh course, in Denver is Sanctuary a real mountain course, other options if you can't get on that are 2 publics, Lakota Canyon or Redlands Mesa.
Galloway is perfect for a Fazio Course.
If you get to Atlanta, Peachtree is special and it will give you a McKenzie/Bobby Jones. Forget about Augusta, don't waste your stationery.
Since you have Doak courses in both Tasmania and New Zealand, that should give you all you need. His best here are Pacific Dunes in Oregon and Ballyneal In Nebraska.
On the drive between SF and Pebble, Pasitempo is special, particularly the back nine, that will give you a McKenzie, restored by Doak.
