The theming/decor in both are different. Boulder Ridge is a little more wilderness with some train theming as well; Copper Creek is more modern wilderness aesthetic. Studios in Boulder Ridge sleep 5; Copper Creek only sleeps 4.
Copper Creek is inside the main building, as it is converted hotel rooms. It’s this quickest to main facilities and services, but can be a bit louder depending on where your room is located or what it overlooks.
Boulder Ridge is a very short walk from the main building, under a covered walkway, and is quieter. It’s closer to the buses, too.
I own at both and love both. I like the quiet and theming of Boulder Ridge and lake views when I get them, but I love having rooms that open into the main lobby of Copper Creek or overlook the pool area.
