We went down for Breakfast (served all day), stayed for coffee and cake, wandered around the museums and exhibitions, took a ride on the coffee pot train, then returned for a light lunch and finished the day with a walk on one of the walktrails. What a day!
Here visiting relatives in the area, so took up your suggestion to take the kids down to the Jetty for a fish. Not expecting anything, but went home with a bucket of great fish. The kids are over the moon. Thanks for suggesting the fishing activity.
