can't remember how we got clearance.....either way- no biggy.
on intl- usually best to always fuel on arrival.
you play golf? if so the "Portmarnock Hotel" is a great hotel/golf course about 10 min from airport.
http://www.portmarnock.com/ very much fun.
then just taxi downtown for the drinking of the guiness or walk down to village of portmarnok. or if enough time rent car upon arrival for great golf excursions- you can have a great time there given enough time and a car.
if not then "Conrad" downtown is good too.
ps- good fbo as last time there 3 yrs ago the apu on our g5 failed to start 1 hr before pax arrival-- no problemo as fbo had a huffer for us within 10 min.
