Starts well, ends poorly–the trip, the book, everything. Worth reading for Heinlein fans, and for anyone who wants a reasonable summary of a mid-50s round-the-world trip. Heinlein has some interesting things to say, is up-front about his prejudices, and is a product of his times. Basically a southern-hemisphere trip, by the way.
Some of the situations described seem to have been used later in his fiction, albeit somewhat reshaped. This is, of course, to be expected.
