Query: In flight confusion

This is by far the worst language-related product I have ever purchased. This CD assumes that you can learn a language by memorizing long, complicated phrases by rote with no foundation whatsoever in vocabulary or grammar. It is just not possible to remember long setences relating to travel without first learning anything about the basic grammar of a language. The phrases aren't even repeated or broken down. This CD might be useful if you have already taken some modern Greek and want to brush up on travel phrases. Otherwise save your money -- most Greeks who work in airports and hotels speak English and this CD won't help you have much of a conversation with anyone who doesn't.
