We have early flights booked in Dublin (735a RyanAir departure) and Edinburgh (645a departure). We are staying in the center of each town at Moxie hotels which don't have front desk help. How early should we leave for the airport for each flight so we have enough time?
Also, should we use Uber or would we have to worry that no one would be available at 430-5a in the morning. I've never used Uber abroad and don't know if it operates the same way as in the U.S. Or, would it be possible to arrange a taxi that early?
