I don't know what the best parkland course with resort is per your criteria, so I will mention a few different models for you:
PGA National in Palm Beach Gardens, Fl: They have 5 golf courses, 5000 homes, a hotel with about 350 rooms+a spa. Housing ranges from $150,000 for a 2 bedroom condo to $1,500,000 higher end homes.
Doral Country Club in Miami, Fl: They have 3 or 4 courses. alot of hotel rooms. Lots of homes but I don't know the details on those.
Reynolds Plantation in Oconee, Ga: They have a Ritz Carlton Hotel, 4 or 5 courses + a new private course. They are out in the sticks, no real city attached like the other 2 above, but they also have a big lake for boating.
Breakers East and West in Palm Beach, Fl: They have an old large classic hotel with a narrow short golf course and condo + a full length golf course about 30 min away with housing.
Barton Creek in Austin, Texas: 2 excellent courses, a first class hotel and very upscale housing, big mansions, high end.
