My aunty just went across there (travelling down from brisbane) while preg (3rd tri) and a 1yr old, 4yr, 6yr, 9yr, 9yr, 13yr... and they loved it! they thought the boat was really kewl expecially the little ones... and they didn't have any hassels with getting the littlies to sleep... The cabins are pretty spacious and comfy.

And my mum goes across it this week with her 4 - (4yrs,9yrs, 13yrs,13yrs)
