Despite what a few reviewers say, I have seen the Imatest numbers for the 70-300 AF-P DX and FX lenses and the FX is optically better, built better, and is 5.6 instead of 6.3 - your trip deserves the BEST ! Yes, it is slightly bigger/heavier.

I agree. The FX version is an excellent lens and works well on DX. If you want to invest slightly more, I have found the Tamron 100-400 to provide great results in a relatively lcompact package.
I would check with the tour orgaizers, however, about lens size. I am pretty sure that your traveling companions will be hauling some big glass for this type of trip, and it is reasonable to think that the tour company expects this. Worth asking.
