Book where young people around the world are chosen to go to the moon

Question

I have a vague memory of reading a book where young people around the world are chosen to go to the moon (I guess like Charlie and the Chocolate Factory or a competition or something along those line). While I don't really remember much else, all I know is they got to the moon where there was a sort of moon base, where the people invited with their accompanying relatives live. I know it's vague but I'm not getting much else from my memory.

Answer 1

It could be Arthur C. Clarke's Islands in the Sky.

young people around the world are chosen to go to the moon (I guess like Charlie and the Chocolate Factory or a competition or something along those line).

From Wikipedia:

At age sixteen, Roy Malcolm has made himself an expert in the history of aviation, so much so that he wins the Aviation Quiz Program, presented on television by World Airways, Inc. Because the prize was described as an all expenses paid trip to “any part of the earth” (rather than on Earth), Roy is able to request a trip to the Inner Station, which is considered part of Earth because its orbit lies under the one-thousand-kilometer limit of earth’s legal territory.

While on the station, he goes to glasses and activities with several cadets his age, and takes part on several missions with them. Later in the book, they go on a rocket trip which makes a pit stop on the moon.
