In my opinion, astro-tourism maybe can contribute to education in astronomy to the public on a wide scale. This can be achieved by providing experiences of using telescopes, observatories, and so on to experience directly how the process of observing celestial objects occurs.
In addition, astro-tourism can also engage the public to help collect data for the research being conducted, and can develop astro-photography programs guided by a team of astronomy experts to spread astronomy education to the wider community.
That's all, maybe it can help answer your questions, if there is something that is not quite right, I apologize.
