Writing is So Not My Day Job

My memory was that it had to do with removing a reference to bedrooms or sleeping or something in one of the tie-in books before it was published. Could be wrong, but it was disappointing. It may have come up again some other time, this idea that the TARDIS is a ship, not the Doctor's home. Except it is. It was in the old series, and it's even more so now. Obviously they eat there, since Rose mentioned running out of milk in TEC. There's no way they stop off in hotels every night :).
