Economy housing tends to be in older buildings and/or to have much smaller rooms.

These are basic rooms with little to no furnishings besides the beds. There is generally limited floor space and the room may feel like a tight space (but you'll be out having fun and connecting with others most of the weekend!). 

These rooms have a single bathroom, but often it is just the toilet and shower behind the closed door. The sink is often in the main area to help with multiple people getting ready.
