When WDW opened in 1971 there was the Contemporary, the Polynesian, and Fort Wilderness. I believe those were followed by the Disney Inn (now Shades of Green). After that my knowledge gets fuzzy, but I think it might be the Swan and Dolphin, CBR, GF, POFQ, Dixie Landings, Boardwalk, YC/BC, WL, CSR, All Stars, AKL, POP and SSR.???
