question:
I had been planning a trip to the Galapagos Islands, and this guide was required reading by the tour group guide. The guide is thorough, providing information of interest and useful for all travelers traveling among islands, but the format of this book severely detracts from any pleasure of seeing them. There's an interactive CD-ROM provided which allows you to see photos that were previously in the book, but not the whole trip. Additionally, there are many grammatical or spelling errors.
