As Ithaca is a college town, bus service by TCAT Tompkins County Area Transit (http://www.tcatbus.com/) is frequent and runs late into the night. Taxi service is an inexpensive way to get around the small city, and it is available by phone, but expect to wait an hour or more on busy or cold nights. Avis & Hertz Rental cars are available at Ithaca Tompkins County Regional Airport, and Enterprise-Rent-A-Car and National Car Rental, in Ithaca. Ithaca also features a Car Share program that offers instant access to a network of cars throughout the city, 24 hours-a-day.
