I wanted to sail up the coast of Australia.
A few days before departure we were advised that because the ship could not obtain max speed we would not get to Yorkey's knob. $100 pp was allocated to our on board account. This was a real letdown as we had planned to rent a car and explore the environs.
In practice I could not cancel the trip because of this as I had already (separately) paid for airfares to Perth and from Brisbane. And so we went.
It was basically good. Our steward was very good.
