James Martin, About.com's European expert, calls Italy home part-time, and though he's no cheapskate, he knows a thing or two about what to see and do in bella Roma. In James's great list of the usual spendthrift's sights (scaling the Spanish Steps, forays to the Forum), get a bonus factoid: an Italian fellow named Roberto Cercelletta makes $180,000 USD scooping a bit more than three coins from the Trevi Fountain annually.
Yeah, so some (okay, all) of what you've heard that there is to do if you're walking on Amsterdam's wilder side are far from free. There's far more to this lovely city than the smoke and sin that get the notoriety, though, and About.com's resident Amsterdam expert, Shannon MacAllister, has put together a great list of free fun from her home in Amsterdam's
Oud Zuid, like the free ferry over the IJ.
Londoner Damian Corrigan spent some time in Spain as a temporary expat, working in hostels and teaching English and finding out what you'll like in beautiful Barcelona, like visiting the fully functioning (yeah, as a hospital) and architecturally gorgeous Hospital de Sant Pau or when the Picasso Museum is free, not to mention the best
