It really depends on what you like to do. There are a lot of beautiful sight-seeing spots and hikes. The Cliff Walk in Newport is great. The Mansions are awesome, though a little pricey. In Providence, walking Benefit Street and Brown U to look at architecture is good. The RISD Museum is free on Sundays. There are some guided tours. Get the info on them at the visitors center at the convention center. Outside Providence, Wickford village is cool to stroll and shop, as are Warren and Bristol.
