I should have noticed the 1990 publication date, but I didn't. It was only after I used the great system for identifying the right spa for me, that I realized how badly outdated this book is. At least three of the recommended spas are nowhere to be found, apparetnly out of business. And of course the pricing and program information is way, way out of date.Some prices are now double those in the book and I found four spas who have radically revised their programs. To top it all off, the cover touts "Thousands of dollars in free coupons for your next spa visit!" The "coupons" look really questionable, and you'd have to spend many thousands at many different resorts in at least six different states to use them all.
