In my opinion, Boulder Ridge is my favorite of the 2. The rooms can be similar to some degree, but Boulder Ridge has a sense of serenity I haven’t found anywhere else on WDW property. The Copper Creek rooms are in the main Wilderness Lodge building, which I found to be very loud. We could hear plumbing from other people’s rooms and they were pumping in “nature sounds” for the pool area that we could hear all night long even with the balcony doors shut.
