My husband and I will be in Cork next March to visit our granddaughter who is doing a semester at UCC. We need to get to Belfast to pick up our tour. Planes seem ridiculous and train makes sense but my reading of the schedules suggests that we can't book anything until 28 days ahead. Is this accurate? We don't want to drive and we don't want to do bus. We're not adverse to changing trains in Dublin. Someone suggested that we might be better off finding a shuttle to Shannon and then flying from Shannon to Belfast. Advice??? Thanks for wahtever info you can provide.
