My daughter and I are thinking about transforming one of our worlds into a Christmas/holiday wonderland for a special Christmas save. Windenburg is our first choice, with Brindleton Bay and Mt. Komorebi also in the running. Mt. K appeals to us because of the winter sports options available. A Christmas market would fit better in Windenburg, though. And Brindleton Bay is beautiful in winter.
We're still looking for Christmasy lots on the Gallery. Lots of them have been posted lately.
