The Ron in Rome website includes a wealth of information about transportation, lodging, and sightseeing. It includes many photos that are helpful in gaining an idea of what things look like "on the ground."
Many first-time and veteran travelers find the Rick Steves series of guidebooks and phrasebooks useful. With clear, easy-to-follow instructions, these guidebooks offer what many others lack: practical information. The Travelers Helpline on the Rick Steves website is a good place to ask questions and search an extensive database for previously-asked questions. Other guides students have found helpful are the Rough Guides, the Let′s Go series, and the Lonely Planet series.
