What is the best, quickest and safest way to get from FCO to my hotel which would probably be by the Vatican (I haven't booked it yet)? I will be arriving late (10:35pm) on February 20th from Paris via EasyJet. I have already contacted Rome Shuttle Limousine and they quoted me 45 Euros there and 40 on the return back to the airport. Is spending that much worth it? I have a 12:10pm flight on Aer Lingus back to the NYC (with a stop in Dublin) on Sunday February 24th.
Also, since my first flight on Aer Lingus is to Dublin, how far in advanced should I get to the airport? 2 or 3 hours in advanced?
