Did a search for B&B's hotels etc in Swords, nothing.

Perhaps bigtyke you had a "wee nip" too many that night? :)

Did find this B&B close to the airport, looked nice.

I think that maybe if we head south first when we arrive, we can come back on the M4 from the west coast and head north around Dublin to Howth and the King Sitric for the last night. It does seem to get applause as a really good seafood restaurant.
