successful visit

An update on the recent visit by our two kids from USA. I had asked earlier for suggestions, and thanks to all who offered opinions.
We ended up taking a shorter trip than originally planned because hubby had to work most of the 2 weeks they were here having just started a new job (poor timing I know).
So they saw photos we had of a recent trip to Banksia Camp in the Walpole area of D'entrecasteaux NP and asked to go there. We spent 3 nights and 4 days there and had a fantastic time. We did some sand 4-wheeling to Cliffy Head and Broke Inlet and a short trip in to Walpole. The rest of the time we enjoyed the incredible ocean views from the camp site, the rocks and the beach and just being together. We saw some great shooting stars at night too.
After we got home, my daughter and i took an impromptu drive to Wave Rock. We thoroughly enjoyed it but only had a very short time there. The family will definitely go back there with a bit more time to look around.
Thanks again to all of you for your input!
