The only issue with River Street is the parking. There is parking at either end, for a price, and in some cases it was difficult to get the kiosk to work correctly. I would highly suggest taking a cab or trolley, get off at one end of River Street and then pick up a cab or trolley at the other end. Another alternative is to book a hotel near River Street so it is within walking distance. Along the street, which is right by the river, there are multiple shops to investigate. You can buy t-shirts, candy, souvenirs, eat lunch/supper, sit and listen to various musicians, catch a dolphin tour or a cruise, etc. There is so much to do! The people are very friendly and helpful.
