We leave from Dublin Airport on Oct 9. Will return the car on morning of Oct 8. Would really like to spend the night of Oct 7/8 at Malahide. It is a pleasant town and we really enjoyed it last time we visited. If we return the car at 9:00 a.m. will there be a bus we can take into Dublin? I know we can take the DART to Malahide after spending the day in Dublin. We would take a cab from Malahide to the airport so we can arrive by 6:00 a.m. Does this sound reasonable?
