Good idea on the sleeping bag.
A few things I've done so far:
1. Buy the Manse Mini-Fridge for my student's room. I've done this with 2 counters and included a sink in the second counter for clean up. Have somewhere to sit and eat as well. This way, you can get up and quickly get breakfast with a Quick Meal (I like the yogurt option).
2. If you can afford it, upgrade the bed! Most of the beds in the dorms are quite low on energy regen. So upgrading the bed will mean your student will get better rest in a shorter time.
3. For socializing, make a group meal in the evenings (or order a pizza) and choose the Call Household to Meal option. For this, it's best if the meal is on a table in the dinning room already. You could set up a small dinning table in the dinning room for this and just move the plate by clicking and dragging it from the counter to the table and then call the household to the meal. This also cuts down on the annoying roommates always crying because they're hungry.
4. Also if you can afford it, upgrade the kitchen equipment to cut down on repairs and increase the quality of the meals so you get hungry less.
5. Stereos - omg there are tons of them in a lot of the dorms. Drove me nuts hearing all of them going so I removed most of them in the rooms and have only one stereo in the building and put a few wall mounted speaks in the public areas of the other floors.
6. Note any 'freebies' laying around in the dorms. Stereos and laptops can be placed in your inventory so you have exclusive use on them. The laptop is particularly useful if you find one in your dorm.
