You may be right, or it could be that the Disney experience is still underpriced for those that enjoy it (for the record, not me).
I say this because they raised prices, lost attendance, but still increased profits. Only when they start to lose money by raising prices are they overpriced.
Part of the current Disney strategy is that they are in an environment of rising wage costs and shortages of employees. Smaller attendance means that fewer employees are needed, so raising prices makes quite a bit of sense — for now.
