The book is a guide for female baby-boomers looking to travel the world, with an emphasis on solo. While I'm a few years younger then a baby-boomer, I still enjoyed this book and thought it would be a great value for travelers of all ages.
While the book does lean towards supporting longer term traveler, the information in it is easily applicable to one or two week vacations too.
They cover all the topics you'll face and in great detail in just 200 pages:
Saving money for your trip, choosing accomidations, travel options, packing, choosing destinations (including what time of year you'll be traveling), dealing with hagglers and beggars, volunteering, reaclimating to home and everything in between.
What's even better they not only cover all of these topics in depth, they offer a wide range of considerations. You're budget is tight, then couchsurfing might be better. Heck, even if you have a bigger budget you might want to go to more expensive destinations and still couchsurf.
Perhaps you want to integrate some cultural experiences into your trip, try a cooking class or language class.
At the end they conclude with checklists (based on time before trip starts), itineraries of varying lengths and what I think is the coolest element that you don't usually see in books like this. Brief interviews with woman who actually did this. How they traveled, what issues they had, budget, and safety. I think this final section sets this book apart from others by adding a human element that makes a trip seem more tangable.
