You're absolutely right that in a vacuum heat stays in because thermal diffusion (conduction) only can happen between a solid, liquid or gas, though. Also, you can lose radiative heat in a vacuum, though that wouldn't be much at all.

Sure, it's drawing heat energy from the room, but it's doing so along with a drop in air pressure. The amount of heat would be going down, but the temperature drop would be very slow, and they'd in the meantime be having difficulty dumping their excess body heat due to the thin air.
