Reservation importance varies
Some major routes strongly reward advance booking while short local crossings may be first-come.
Arrive by the required cutoff
A reservation can be lost if the vehicle misses check-in rules.
Vehicle dimensions matter
Oversize vehicles, trailers and roof loads can affect fares or acceptance.
Weather can disrupt schedules
Keep an alternate overnight or travel plan when a ferry is a critical link.
