I bought this in the airport on the way to a holiday abroad. I have not laughed so much for a long time.
There's an element of truth in what he says, with regards to the hassle of going on holiday at home or abroad, the worry about your house and pets whilst you are there and of course, how the locals view you when you are there.
Yes, the book is "samey" in that the central theme is that it doesn't matter where you go, there is no place like home, but it doesn't spoil the book in the least. This book was passed from myself, to my husband, then I bought a copy for my mother in law (because she was down at not being able to go abroad this year) and we've all hooted and cried laughing at various parts.
If you buy this book, particularly at the sinfully low price they are often sold for, you will not regret it, I guarantee.
