When you travel to major cities, thecost of lodging can be sky-high. Onesolution is to scout out cheaper digs inthe city's suburbs and take mass transitinto the metropolis. This strategy can bea money-saver in American cities thathave well-developed and reliable transitsystems (eg, New York, Boston, and SanFrancisco), but it works in many foreigndestinations too. If you're traveling toDublin, for example, a room in DunLaoghaire, just south of the city, can offeryou a spectacular view of Dublin Bay ata fraction of the cost of a room in aDublin hotel. It's only a 20-minute trainride from the center of town via theDublin Area Rapid Transit system.
