If the bar prices are reasonable you can get lagered up onboard ship
I think they've thought of that! T&Cs "Passengers are not permitted to bring luggage"! As regards, buying a 2nd ticket, the deal is also available from Dublin to Holyhead for €6.50 from stenaline.ie.
wow really ? that should be in their T&C's then.
That has never happened to me when travelling as a foot passenger.
