costs are outdated

I bought two books for my upcoming cruise to Alaska. I thought this specific book would help me save money by doing excursions on my own. But the very first show I signed up for using information in this book was not the same price as quoted in the book. It was my fault for not paying attention to the publishing date. This book was published in 2011 and the prices have inflated by now. So, while the walking tours are informative, don't expect the prices to be right.
