The theme seems to be similar: a park was built once -> lot of people used it -> repairs/maintenance was not done or was not done enough -> park got dangerous due to neglect -> less people visit it -> park gets closed down

I wonder what could be done differently

If something is literally a novelty, there's an inherent boom-and-bust dynamic to that. Travelling fairs are one alternative for places that don't have enough demand to sustain a permanent amusement park, but those have their own issues.
