Do you use 5D III plus 24-105 as travel camera?

I think the 24-105 is a great travel lens.  I have taken so many photographs that give me happiness with this lens.  If I was on assignment, sure I might bring more lenses.  But if I am with the family going to a place I will never go again, the 24-105 is a great one lens solution.

I distinctly recall shooting in St. Peter's at 1/5th sec and coming away with stunning keepers.  To me, IS is mandatory.
