Absolutely littered with factual errors, for example "ship such-and-such has no balcony cabins" when it in fact does. I have been on many, many ships and when comparing those to the books descriptions, estimate there may be in the HUNDREDS of errors in the complete book. The ratings are also very uneven, as the author fell into their own trap of trying to use a very sophisticated rating system and then fails to apply it evenly. For example, one ship with small cabins claims that they are all "suites", and he points that out, whereas with another ship and the same situation he does not. This 600+ page mess, along with the arrogant "ultra expert" tone, when in fact I don't think this guy has been on most of these ships ever, really does make Berlitz Publishing a ship of fools.
