My wife wants to travel again in 4-5 years, probably Scotland next time. Maybe we should put our names in the hat and see if we have a table by then. Might be worth a ferry ride and a drive over.
They have cancellations page. You might get lucky.
I have to admit - that page looked different yesterday!
