We purchased SSR in '06. After 5 trips we'll be making our first stay elsewhere this October (trying BWV for a few days before SSR).
We visit the other resorts, usually for a meal, but SSR is more homey to us. I can't miss those long scenic walks and very accessible pool. It just feels like we're at an exclusive resort that just happens to be near a crowded theme park.
And when we bought, we initially thought we'd be like gypsies trying them all. But when VWL was booked for December and we ended up at SSR, we got seduced.
