I would take the 700, the fx format seems like it is better suited for travel photography, and I think after 2 Europe trips carrying around the 70-200 that I would not bring it again. Most of my shots were composed under 100mm, but I was using a cropped sensor camera so with the d700 you may want more reach.... Wait now there is a good argument for the d7000 instead. I would also think a lot about your bag, I converted an old Crumpler brand messenger bag, and it worked greAt, hangs at your side and one flap access. Now I see Crumpler makes a dedicated dslr bag - mid sized one is called the " six million dollar home". That would be a good purchase for travel IMO. Have fun over there.
