We had a group booking of over 20 family members celebrating birthdays. We had a short cruise - Sydney to Morton Bay and back. I think we all felt the same about the following.
Flying fox, (which is pictured on all the advertising of the Jewel) - and which I thought would have been a highlight for the younger was $30 a go. Very expensive for a few seconds of thrill. If a family has two or three children, this is way too expensive, and the flying fox was hardly used on our trip. A sure sign that most people couldn't afford it.
The meals were small and very, very average.
Whilst the cabin was tired and needed an update, it was very clean and presentable
