Agreed, although it’s wise to have a backup option for this. It’s entirely possible that you have two solid Portal players go at this, which should be a really fun romp. However, in my experience, any skill gap between the players usually turns every stage into “how do I carry my friend through this puzzle?” An extreme version of this can be seen in Game Grumps’ playthrough.
Even an arrest record can be a problem. Which is itself, a problem.
