Jean, We made the trip several years since, choices are Catmaran type car ferry which takes about 3 hours and leaves from landing stage or leisurely overnight ferry leaves around 9:00a and arrives 0:600a on this one even though we booked in advance from USA our cabins had been given to a couple of truck drivers. Getting off the ferry @ 06:00a is no fun for Ireland is deadsville @ that time and does not stir until a decent hour* and you cannot buy breakfast or check into a B&B etc., pete Fares are posted on web look for Dublin - Liverpool ferry crossings, you'll find them all. *10.00a
