Heads in Beds is supposed to be the Kitchen Confidential of the hotel world, full of tips on how to get upgrades and what not to say to bellmen and the people who check you in. Meh. I guess I don't travel enough to care about what hotel staff are really thinking. I always use the U-Scan at the grocery store and would be happy with a totally self-check hotel where you cut your own keys and haul your own bags. If you're interested in learning how to slip the front desk guy $20 or $100 for a "free" upgrade or bottle of wine, then this is the book for you.
