Nothing says "on vacation" like devouring a Harry Potter story in a single day. The "book" is really a script for two plays, plays that are selling for astronomical ticket prices in London. You couldn't see ome of the plays without seeing the other, and you probably do not get much from the story if you have not read the original series.
Between this and the Magical Beasts trailer, it is nice to have Harry stories back.
One more vacation book to come.
