Hmm, an interesting intermediate chapter between the first act and the second one. I daresay all those visiting or seeking to become citizens of Luna are going to be rather taken by surprise by some of the social organizations there. I've in mind the various bits of Lunar civilzation shown in "The Moon is A Harsh Mistress" and other works by Rogert A. Heinlein.
It should be interesting to see what the Weasleys and Hermione have in mind. I wouldn't be surprised to find Luna and Neville already have places on the moon and "just" never bothered to tell anyone around them.
I'm looking forward to the next few chapters and all the "fun and games". I'm sure neither Fudge nor Dumbles is going to easily accept the Lunar refusal to pay for the destruction of part of Hogwarts. But, you don't meet the contracted conditions, you don't get what was promised if you did.
