DVC will currently allow it but it is over the occupancy limits for the unit. The reasons why it is bad is far too complicated and controversial to go through again but include wear and tear on the units and overall density of the resort, restaurants, parking, pool, etc.
To answer the OPs question: Yes, Member Services are currently allowing 5 people in a one bedroom unit. The resort does not provide any rollaway beds, bed linens, or towels for thr 5th person.
Occupany is a hot topic here on the DVC boards and is lmited to this thread: DVC Occupany Thread You may continue this discussion there if you wish. This thread is closed.
