Other forms: itineraries
An itinerary is the written plan of a trip — where you go, on which day, and at what time. Printed out by a travel agent and taped inside a folder: Tuesday, ferry at 07:40; Wednesday, the castle, then the night train.
An itinerary is the document, and it is also the route itself: their itinerary took them through three countries. The word belongs to organised travel — tours, business trips, a president's visit — so it sounds heavy for a weekend at your cousin's. Do not mix it up with itinerant, an adjective meaning moving from place to place for work (an itinerant preacher). And mind the shape of it: five syllables, i-TIN-er-a-ry, with an -ary at the end that people swallow and then misspell as 'itinery'.

itinerary is a travel plan.
Latin iter meant a way or a journey, and an itinerārium was a road-book: an account of a journey, written down. Middle English took it in as itinerarie and kept the meaning almost untouched. The whole line goes back to a Proto-Indo-European root, *h₁ey-.
