Query: Excellent if you already have some Spanish ability

I really like this book. Fits perfectly in your handbag or saddlebag out on the trail. All the basics are covered here and even some things you may never need to say at all - such as various pick up line in bars! There is a nice sense of humor paired with common sense throughout this phrasebook. However, if you need to find a particular word for a particular item you will need a true Engligh/Spanish dictionary rather than a phrasebook. I carry both with me almost constantly.
