You lost me on this one. It suggests other things to me.

But to add to the good advise you just got... let me suggest that you not go on vacation with either a camera or a film that you are not familiar with. Otherwise, use Portra, box speed, meter with your camera... and forget all of "the fancy stuff". Focus on the image and the memories.
