We are planning to visit Nantucket (probably in mid-Sept) and will have a rental car. I'd appreciate the name(s) of ferry's that offer this service from the mainland.
Also how long should we plan to stay? We are active seniors and are trying to see as much as we can while we can. We will start in Providence and visit Newport, Block Island, Nantucket, Martha's Vinyard and Cape Cod. We are avid photographers and interested in scenics, sunrise & sunset, and "touristy" things (mostly outdoors). We are not interested in art places, libraries, lying on a beach or late-night partying. This will be a sight-seeing trip and not a vacation.
Also we would be interested in a guilded tour.
