Every Saturday in The Independent's award-winning Traveller section, our "48 hours" stories explore new and exciting city-break itineraries. Now, 25 years after the series was first launched, we've produced this special, designed to help you get the most from a visit to a selection of 20 key North American cities. Among them, you can choose from New York's dizzying nightlife, the rollercoaster thrills of Orlando, the Hollywood glitter of Los Angeles or Vancouver's great outdoors. We've also included a range of accommodation options to suit your budget.
