From Stena's website:
"Stena Line are pleased to announce that from Monday 1st April 2013 foot passenger will be able to travel on the 02:15hrs and 15:10hrs sailings from Dublin Port!"
With the Nordica having been in place since 2008, why has it taken this long? Good news though. The availability of the 0215 from Dublin port and 2030 from Holyhead offer some new Sail 'n' Rail travel opportunities.
