Transportation in New York City can be expensive and time-consuming. Consider purchasing a MetroCard for unlimited subway and bus rides. Walk or take the subway whenever possible to avoid traffic. Taxis and ride-sharing services are readily available but can be costly during peak hours. Expect to spend around $30-$50 in total transportation costs for the duration of the trip.
If you have more time, consider visiting the Empire State Building or the Top of the Rock for stunning panoramic views. The High Line is also a must-see for a unique urban park experience. If you have less time, consider skipping some of the indoor museums and spending more time exploring the city streets and neighborhoods. Don't forget to try the famous New York bagels and pizza!
