Your question is sort of vague. Are you taking the two zooms you mentioned? Or do you want to leave those two and bring one of the ones you mentioned as options? Or are you bringing both zooms and want one more lens?
I would say, just bring a 24-105. It's good enough in the quality department and gives you both decent wide angle and a little telephoto. My second choice would be the 24-70 f4 IS and my third the 30mm 1.4. (This is assuming you are leaving the two zooms you own at home, which is what I think you are saying.)
I would bring the zooms leaving the 70-200 in the room for a few days. Just looking for a few lighter gear days so was thinking 24-70 f4 is, 35mm prime like the f2 is or other suggestions. I am all about getting mickey and my twins in focus so wide apertures are not going to help me with that i usually sit 5.6-10 when shooting outdoors to get them in focus.
