We were a group of two families visiting Port Macquarie for a family holiday. We loved the house, and how well it was set up for families, including a games room, two cots (thanks!), lots of toys, and some gates to keep small children off the stairs. Proximity to the beach was particularly nice.
Only (very slight) downside was the small amount of road noise. You wouldn't think so from the map, but the road does get some traffic during the day (it drops off at night though).
