It's been a few years, so I'm refamiliarizing myself with the Irish Ferries website. My one question is, does sail-rail tickets generally become available in the same 8-12 week window that UK rail ticket become available? I can book a ferry crossing 13 months out, but can only do a rail-sail booking 6 weeks out to December 31. Nothing available yet January 1 or after.
I'm aware of past issues with port repair work and TfW, not concerned with those.
