Boston travel tips
In Boston, it is customary to tip for various small services: a maid, a car valet, a cloakroom attendant, and a doorman will expect $1-2 for their services. A hotel porter will take care of your belongings for $1-5, depending on the weight and size of your luggage.
The North End area is also called Little Italy in Boston. The Italian community lives here, and you will hear more Italian here than English. Walk along charming houses with Italian courtyards and taste the best gelato outside Italy at Lulu's Sweet Shoppe.
When you're tired of the Boston overland routes, catch a ferry at Long Wharf and head to the islands in Boston Harbor. The Boston Harbor National Park recreation area unites 34 islands, 11 of which are open to the public. Beaches, ancient lighthouses, military fortifications, and even a former prison await you for only $17.
