Many Worldmark resorts are on the smallish side. Gleneden on the Oregon Coast is a favorite of many WM owners (although I prefer Depoe Bay, which is larger, but has guaranteed ocean views.) WM Discovery Bay, Deer Harbor, and Leavenworth are other nice resorts that don't feel large. We just visited Manteo Beach Resort in B.C. and found it small but lovely. Many years ago we exchanged into RHC Lake Placid Club Lodges in NY, and found those homey.
In CA, we appreciated the privacy of the tiny cottages at Riverpointe Napa. I would have added Coronado Beach Resort as a favorite small resort, but the OP already knows about that one, being an owner there.
When it's just my husband and I, we prefer smaller resorts, but when we travel with the grandkids (boys 6 and 9), we exchange into the mega resorts for their swimming pools and activities.
Another vote for Worldmark points. Worldmark has more than 80 resorts to choose from. They are always clean and nice. Most of them are very spacious, with the exception of a few - like the Vancouver city's location. Fully equipped kitchen, with array of spices, usually has a private grill on the balcony, although we don't generally grill outdoors. Reasonable maintenance fees. The resort is as large or as small as you want it to be. I don't join on site activities regardless of the kind of resort (Marriott, Westin, Worldmark etc..) that I stay at.
