Hi there, have only driven there once before but have to say its not nearly as bad as you'd think!
At the time l was the only one old enough to hire the 8 seater van (21+ l think?) so didn't have much choice about it. Had never driven out of the UK, an automatic, or anything that big so l was a bit apprehensive to say the least
The drive from the airport was pretty much enough to make me realise it's not that different, although l will admit to accidentally going on the wrong side of road once

Trust me if you do it once you wont do it again, be calm and don't panic if you do
Biggest tips l could give are:
Take it steady! As someone else said, make extra checks pulling out of junctions and unmarked crossroads.
Look out for road signs. A few times l found l just couldn't get over to the right lane in enough time, and if you miss your exit it's not as easy as it is here to correct yourself.
I'm due back again soon and again will be doing all the driving, this time just because no one else wants to. We've got a 15 seater van this time, so parking that should be fun!
Enjoy!
