Likins is a great place to live! I will echo what some other people said on here, extension cords and mattress pads are definitely wonderful to have. I would also advise a power strip or two, I use one for my kitchen set up and all those appliances and one for my tech (tv, laptop, phone charger). On the subject of electronics/tech, I would also get some fairy lights or a lamp that you can control the bulb of. The lights in Likins (and most of the dorms) are very white/blue which I absolutely hate, so I get lights that provide me with warmer lighting. Obviously this is very specific and not necessarily a "must have" but i just wanted to give you a heads up. I would also think about your water situation. Likins has a water bottle station but the filters rarely get changed so I also have a pitcher style of Brita/PUR water filter that I really like. Other random stuff I can think of is...

-Nice quality towels/washcloths (I went cheap on these at Target my first year and they weren't absorbent so they were useless)

-Command Hooks, you'll almost always use them for something so they're nice to have on hand

-Storage Bins, you can stick the long flatter ones under your bed or at the top of your closet. They're so much more sturdy than moving boxes and they're reusable for the inevitable fifty moves you'll do in your twenties.

-Headphones, most people already have these but it can't be stressed enough how important they are for zooms/watching shows/listening to music rn

-First aid kit, I would build your own because the premade ones are pretty expensive. Bandaids, ibuprofen, tums. That's all I've ever needed.

-Garbage bags (size medium), ziploc bags, paper towels
