Get your luggage, exit arrivals at Trenton, NJ Airport (TTN-Mercer), and collect your rental car. Which one you hop into depends on where you’re going. If you’ll be spending the majority of the time driving in downtown Trenton, around 5 miles from the terminal, choose something zippy and small. A compact car that’s easy to handle will be ideal for navigating those bustling city streets. But with so many things to see, like the gorgeous sandy shores of the region, you may want to add some pit stops. A larger vehicle, like a full-size car or an SUV, will make lengthier road trips more comfortable.
