One of the big draws, for us, with UA was the suite style dorms. We really thought our son would need the space having grown up a homeschooler for the most part and always with his own room.
Well, in a last minute turn of events, DS ended up at UF in a traditional style dorm with a roommate, communal bath, et al. Guess what, he loves it!
I do think it’s a good idea to try and match up at least a little with prospective roommates. That being said, my son went totally random at Preview (orientation overnight) and got along great with his roommate. He gets along great with his current roommate too. They are enough alike to be compatible, but they each have their own interests too.
You will be fine. Trust the process and your own ability to be adaptable and resilient.
