We have stayed at the resort twice a year for many years. Other than an occasional group, we seldom see more than a few people in Sonz. Have never tried it as it's rather pricey. It changes its name to Swan Court for breakfast and it's quite good, but also pricey ($29 pp for the buffet I believe) unless it's included in your room rate. It's wonderful to have breakfast there adjacent to the lagoon with the swans and ducks in it.
