Fewer than 100 people have been allowed inside Movile, a number comparable to those who have been to the Moon.
BBC reporting is really kind of crappy. 12 people walked on the Moon; 22 people orbited the Moon.

Is BB(26) - BB(25) greater than or less than BB(25)?
In fact I would be willing to bet serious money that BB(n+1)/BB(n) is greater than BB(n) if 3 < n.
(This is, of course, assuming that one assumes that BB(n) is well-defined. That is an interesting point of philosophy given the existence of Turing machines which can't be proven to not halt.)
BB(n) grows faster than any computable function. In order for BB(n+1)/BB(n) > BB(n) to hold, BB(n) merely has to grow faster than a sequence whose new terms are obtained by repeated squaring (like k^2ⁿ). That's computable, indeed primitive recursive, so BB(n) definitely grows dramatically faster than it.

Edit: another way of looking at this is that the Ackermann function grows unbelievably faster than functions that easily satisfy the property you describe, and the Busy Beaver function grows unbelievably faster than the Ackermann function. Somehow putting it this way feels like an understatement, though!
However you have encapsulated the reason why I would be confident of this result. :-)
100 people: 0.00000134736% of the earth's population
Seems fairly comparable to me.
"How many people are coming over for dinner tonight?"
"Oh, not too many, just about 2.8070175e-10%"
"Ahh, so one chicken will do"
Do you mean Apollo 13? It had three astronauts on board.
