We actually changed it to be more like the earlier editions in that you can attack from within and without. Creatures can't pass, but objects and spells can. A 50 mph gust of wind will destroy it.
We did modify it so that it's invisible from the outside, so it still makes a safer camp, but not impenetrable. Sounds and light don't exit it, and it keeps you warm, so it still works very well.
The basic problem we had is that it pretty much eliminated anything interesting from happening when camping out at night. Seemed way overpowered for a low level spell. At least that was our take on it. Other groups probably don't want to bother with potential night-time encounters, in which case it's great as written.
The players had fun when they realized (on their own) that they had to walk through the several inches of snow that had fallen the night before when they left. Cartoon body-shape in the snow!
