Starting my first year at the University of Iowa this upcoming Fall and I wanted to see if you guys had any useful tips or advice for a freshman moving into a Single Dorm room? Maybe you could share some stories from your son/daughter’s experiences with a single rather than a double. Any little nuggets would be great

For my D, a single was a negative experience because she was too isolated - she had a harder time meeting and getting to know people because it was too easy to be by herself. So, my advice is to bring a door stop and keep your door open as much as possible the first few weeks. Hang out in the hallway or in any shared lounge or group space. Go to every RA meet and greet or dorm run event. Join some clubs that will get you out of your room in the evening. Then, once you’ve met and made some friends, enjoy coming back to your quiet space!
D loved her first-year tiny single – she kept her door open when she was up for company but was glad to have a space to retreat to when she needed it. We sent care packages with treats to share, which always helps make friends 
Both of my kids had a single first year. They loved it. They kept the door open when they wanted company, and had it closed when they wanted some privacy. I was spared from a lot of roommate drama the first year. Sophomore year when they had to share a room at their sorority house, I heard a lot about “making too much noise in the morning,” “boyfriend visiting and she wants me to move out,” “roommate being too messy,” “roommate borrowing stuff without permission.” The list just went on.
Tell your kid to have food (or drinks) in her room, and she won’t lack company.
I have a friend who kept her ds supplied with candy to keep his top dresser drawer filled. As long as the door and drawer were open, people knew to come in and help themselves.
I too will be a freshie in a few months and will (hopefully) have a single. I’m not afraid of talking to others, but I would prefer to be alone and have quiet time whenever I want.
Bring something to keep the door open when you are looking for company.
My D is finishing up her first year at Penn in a single, and loved it. At first she was disappointed, but right away realized the enormity of having that kind of privacy when she wanted it. Everyone on her hall ended up being friends so that helped as well (and there were many other single rooms.)
