I agree that Arwen was making a permament choice when she chose mortality. She could not simply sail to Valinor following Aragorn's death and reclaim her immortality.

Bur, assuming that there was a boat to take her and with the grace of the Valar, it would, I suppose, have been possible for her to sail to Valinor to see her father and mother one last time before she died the mortal death that she had chosen.
