We had a wonderful time at SA SONCA. If you're a large group (like we were) it's really comfortable to have two dishwashers, two full kitchens, 4 bathrooms. There are two big apartments and everything is in doubles if you rent the whole place.
Kids loved it: pool, table tennis, lot's of land around the house to play.
Apart from the caves, many of the Mallorca's sites are located on the other part of island. We rented a car and we didn't mind driving around. The roads were empty in late October so those were nice easy drives.
