You'll need a car to get from one area of Miami to another. It's pretty sprawled out. If you're staying in South Beach, don't worry about a car. You have all the restaurants, attractions, nightlife and daytime activities at your fingertips. These meet at Miami Avenue, which separates east from west, and Flagler Street, which separates north from south.
Roads run diagonally, northwest-southeast.
Don't be afraid to ask for directions. As for taxis, beware. We don't put it past a Miami cab driver to take advantage of tourists. Costs Florida's high season is during the winter. You can expect hotel prices in Miami to skyrocket during this time.
