Echoes of Terry Pratchett:

Archaeologists are excited for this find because it comes with a visitor's center and a parking lot.

Or echoes of Douglas Adams: it’s been undiscovered by the archaeologists, because they couldn’t afford to stay there.[0]

>"Han Wavel is a world which consists largely of fabulous ultraluxury hotels and casinos, all of which have been formed by the natural erosion of wind and rain. The chances of this happening are more or less one to infinity against. Little is known of how this came about because none of the geophysicists, probability statisticians, meteoranalysts or bizzarrologists who are so keen to research it can afford to stay there."

Looking at a couple other articles I gather that it was announced as open to the public? Another article mentioned that they have been working on the site for over 8 years: https://www.reuters.com/science/archaeologists-peru-unveil-3...

If it's announced now after eight years' work there 'visitor' may mean more like academic visitors, visiting archaeologists, even those working there full time need somewhere to park, etc.

Because now it has been "unveiled"! I guess it was wrapped in cellophane before...

Probably timed to coincide with the peak of the tourist season in Peru. Dry season is May-Oct (not at all advisable to visit Machu Picchu in the wet season). Jul-Aug is summer holidays for Europeans, who are the biggest cohort of international tourists in Peru (and summer holidays for North Americans). And Peru's independence day is 28 Jul, so locals take an (often extended) long weekend, so a bit of a spike in domestic tourism coming up too.

Stealth visitor center?
