The common advice here seems to be "buy where you want to stay". You'll have 11 months ahead to book at your home resort, but only 7 at other properties, and as SSR gets bigger, the small resorts will become harder to book. They may be impossible to book at busy times. We bought at OKW b/c we love it there, and figure we will always be happy to stay there, and occasionally try other resorts too if there is availability. Make sure you like SSR enough to stay there in case that is your only option.
