Whenever it is actually safe to travel, and enjoy these types of experiences, I highly recommend this adventure and many other Train Travel Experiences around the World.
You know these kind of things, for now, they should offer 3D paid experiences, so people can do it now. They make money to offset lack of physical bookings. People from ALL over the WORLD can see it now, from the comfort of their home. It can be an educational experience. Even make some sort of ‘Experience Momento Box’, a promotional box. Include a discount coupon, for later use to take a physical Train Ride Excursion.
I think Museums, Zoos, Galleries, Tours, Plays, Musicals, and the like should do this.
