My son was (essentially) an only child (he has a much younger half brother, but they never lived in the same home). So the suite style dorm was great for him. He was always used to having his own space to retreat to.
Others say the traditional dorms are more social and I’m sure that’s true. I know when I was a student many years ago in a traditional dorm we’d often leave the door to the room open to interact with people going through the hallway. But I had several issues with roommates during my college years and know what that’s like too, so I also appreciated that my son also was able to keep personal things locked in his room.
My son may have met more people in a traditional style dorm, but he was still able to meet others living in a suite. He became close friends with the group that lived in the suite just across the hall from his and moved off campus with 3 of them the following year.
You just have to decide what you think will work best for you.
