Family Vacations: Top Spots

From Teresa Plowright, former About.com Guide

London is one of the easiest places in Europe for North Americans to visit for a family vacation: we speak the language, the "tube" underground subway is easy to use, kids are already familiar with London through movies and books, and London's major museums -- including the kid-pleasing Science Museum and Museum of Natural History -- are free.

Granted, London can be expensive. Fortunately, our About.com Guide for London has suggestions for budget-friendly lodgings, and also has a list of over 100 Free Things to Do in London.
