We will be staying with family in London for a month. We previously lived in the UK, so have done many of the touristy things there, and a friend has invited us up to their family home in Bangor. How many days is needed to do Bangor and Belfast. We would like to see the Giants Causeway and am also debating whether or not to take the ferry over to Glasgow. Don't want to be away from London for too long, but don't want to shortchange Ireland. What would be the recommended time and also the short-don't miss list.
Thanks in advance.
