Hi, Im 23 and have lived in RI my entire life. Ive pretty much been everywhere in Providence so I can tell you a few good places.
Definitely check out Thayer St. on the eastside. Lots of restaurants/bars (bistros) for late night like KartaBar (my favorite), ViVa, Paragon, Andreas, Liquid Lounge. Theres also Starbucks, Tealuxe, Antonios has AWESOME pizza, and a few shops. Also Wickenden St. which is near Thayer has some nice late night spots and coffee shops. This is all in College Hill so you get a lot of young people in their twenties. Federal Hill is good for fine dining.. Pastiche is a nice dessert/coffee shop. Providence Place mall is huge and also has a few good restaurants and also Dave n Busters. Downtown there are a ton of nice restaurants.. many that turn into a nightclub or a social spot to get a drink like McFaddens, RiRa, 10 Steak and Sushi, Olives, XO Cafe, Parkside, Fish Co., Moda, Tazza etc. Theres ice skating in the center of Providence and Waterfire which usually starts around May.
As far as golfing theres a place in South Attleboro, one at Goddard Park which is in East Greenwich/North Kingstown, a driving range in Smithfield and I know theres mini golf in Cranston so there might be a range there too.
Newport is beautiful and definitely a place to see. You can spend an entire weekend there going to the shops, restaurants, mansions, cliffwalk, etc.
Hope you have fun
