Thank you so much for your replies, much appreciated. I'm currently sat in 20 A outbound to DXB then in first in 1A coming home.
I think ill stick to my seat for business, as I had an image of me sat wasting away and not being able to get to that awesome bar as quickly

And get those fab engine shots when I am in first on the way home
Beyond excited, it's been my geeky dream to fly the A380 and drink in the bar and have the shower on my way back. November needs to hurry up!! 😊
