A checklist for the man about town who plans to be a man about Europe. Kenneth Morgan's do's and don'ts are to the point, as he ticks off the necessities, from hotel reservations (book the best room in the best hotel) to luggage (Hartmann's Cally Ho is easy to spot). Tips on eating, drinking (including that 60 proof Scotch in England), tipping (generally stick to the equivalent of a quarter) nightclubs and ghtseeing, also in-the- field transportation (rent a car but don't expect to economise), plus a currency guide add up to a book that is negatively positive since many of it recommendations are restraints. Men will appreciate it.
