Presumably if their cost base and their prices rose by the same percentage, their profits would get bigger, although they wouldn't necessarily be worth anymore in real terms. But yes, if their prices rose by a smaller percentage than their cost base, it could be a different issue. In theory spend per a head often reduces when a park gets too busy, because people are less likely to buy things when the queues are longer. Liseberg is also different because you can pay to enter without buying a wristband for the rides, so maybe the mix of guests changed.
Having said that, when you work in parks you often realise that claims made in press statements and on LinkedIn can be far removed from what's actually happening. If everything on LinkedIn were true, all the British theme parks would be absolute cash cows, which doesn't really explain why they keep on closing down. And the stories on LinkedIn often don't reflect the reviews on Trip Advisor. Because Liseberg's owned by the city is does tend to be a lot more transparent than most parks, so hopefully any information coming from the park is honest and accurate.
