Do you want to be closer to your children or your parents? If your children I would say look around the area between Abergele and Llandudno. By the sea, good shops, not too far (about 30 minutes by car)from your daughter and close to your son and a beautiful area. If you want to be between your children and your parents I’m not sure how you can do that and still be near the coast, maybe others have more knowledge than me?
