We spent the first week of our holiday at Pine Lake Marina. We were worried about coming from a resort which is clearly family friendly to a home with less amenities. It worked out though. The cottage is obviously smaller than the main house (and we would definitely, with the benefit of hindsight, have preferred to stay in the main house), but we still had an enjoyable stay. There are 3 bedrooms in the cottage, and a living area. That suited our needs (5 adults and 2 toddlers), but the kitchen was a little on the small side. There is a nice outside area with sufficient place for the kids to run around. And the area is very peaceful, and safe to walk about. We swam in the estuary, although we were worried about the cleanliness of the water, at times.
The cottage was serviced during the time of our stay. It's really invaluable having someone to keep the place clean.
