I’m going to the orientation in a week. I can let you guys know how it went. So far I’m planning on bringing some change of clothes, toothbrush, stuff like that. I hear they already give you a blanket and pillow, and since I’m coming from a plane I don’t want to carry too much. Besides that I hear bring snacks because they either give you lunch really early or reallly late. I’m also going to bring my ID, because they need it to give you your student ID. 
Oh and I’ll be bringing my laptop because you need a way to access SISWeb so you can build your schedule and sign up for classes. If you don’t have a laptop you can always use a smart phone, but I hear laptops make it way easier.
