Niall,
Newport is a truly unique experience in New England, if not the entire east coast. The course generally runs hard, playing generally firm and fast. The site is generally treeless, making the wind and weather very important. There are few courses that have the same type of history and "links feel" that are located north of Long Island. The holes are wide open with long rough to the far outsides, and the greens generally accept ground shots as well as those in the air. The bunkers are many, random, and deep, and they are filled with a unique local beach sand that could be described as a fine gravel.
As far as I know, the course's origins were found at the very beginning of golf course design in the US. Ross modified and expanded this original layout, and Tillinghast totally revamped it to the point where the Ross influence (beyond spiritual) is minimal today. I would be interested to see/know why Tillie was called in relatively soon after Ross's redesign, and if it had more to do with logistics than anything else.
And they do not have lodging.
