I don't expect to really finish it off with everything until spring. Can't really stain/poly in my house and it's winter now in MN.
If you aren't set on using poly, you could try shellac. It's alcohol based, so it dries quickly with very little fumes.
I'm using it right now to finish my 40B stand, and I'm building it in a studio apartment.
The Shellac seems to be fairly easy to use, and somewhat forgiving. And from what I've read, it should be easy to repair any scratches/issues later on.
