We stayed next door at Fortuna de Oro, both Cal-Am, and will return Nov 1. The ballroom/concert area at Sundance is very nice. The new sports area looks good. They were still finishing the new pool last winter when we were there. We prefer Fortuna because of the on-site restaurant, golf course, large pool with happy hour dancing available every weekday. Sundance does have some happy hours & offers concerts in their ballroom. Enjoy Yuma!
