The Thrifty Guide to Ancient Greece: A Handbook for Time Travelers is a snappy, informative travel guide that comes in the package with your time machine purchase in the year 2163. It contains information vital to the sensible time traveller:
How can I find a decent tunic that won't break my bank account?
Where can I score cheap theater tickets in ancient Athens?
What do I do if I'm being attacked by an army of five million Persians?
This book is designed as a parody of Fodor's, complete with humorous maps, reviews of places to stay and top attractions (Don't miss the first-ever Olympics!), and tips on whom to have lunch with (Alexander the Great and his horse, Bucephalus, naturally). If you had a time travel machine and could take a vacation anywhere in history, this is the only guidebook you would need.
