We will be flying out of Shannon Airport to London at 1:00pm (11:00) on a Wednesday in late September. The drive time from our B&B in Dingle, according to Google, is 2.5 hours. We plan to leave at 8:30am and should arrive at 11:00am according to this. That will give us 2 hours to return the rental car and get to our gate.
Does anyone have any insight to this plan to help me save time, avoid issues?
Is there a high risk of a lot of traffic I should be concerned about?
Is it fairly easy to return a rental car and get through security, etc at Shannon Airport?
