Going to be in Newport for 4 days. From what I've read online, it looks like the Newport Trolley won't be running while we're there...5-17 to 5-21. We're big walkers but also like to have the option of hopping on a bus/trolley if we get exhausted or need to reach another location in a hurry. We've rented a car for one day and I'm now wondering if we should add another day to our car rental. Our goal is a more relaxing vacation vs a ton of walking each day. We want to explore as much as we can of what Newport has to offer. We are staying just a few blocks South of Thames. Any advice/tips would be much appreciated!!
