We are a family of 5 (2 adults, 2 children - 7 & 10 , 1 elderly) heading from Perth to Albany from 21 Dec to 23 Dec. We will be staying at Ace Motor Inn. We would like to visit the Tree Top walk and the Lavender and Berries farm. How should we plan our route and how much time is required for each place? Any other must see places, given our limited time in Albany? Thanks!
