Reached the airport plenty ahead of time despite terrible traffic A55 (main highway of north Wales).
Had seats on the upper deck of the A380 Bus. Surprisingly good experience because of less seats on the upper deck, there is less congestion to get into the plan.
As usual, watched plenty of movies and get as much sleep as possible.
Lucky us, we have 4 seats all to ourselves. Took turns sleeping lying down completely flat. Best flight sleep I had ever.
