You will love it!!
I agree with all the points everyone else has already posted. I "borrowed" the gold "suite guide" book on a flight a couple of weeks ago, and realised I missed the pen

I'll be flying on EK1 next week, so will make up for that!!
The biggest problem I had was trying to contain my massive grin.
I didn't manage to do that, but did close the doors for a while just to let it all out, whilst I tucked in to my Iranian caviar!
I fly a fair bit, and it's a long time since I've been that excited to fly - really looking forward to the return journey.
Oh, and one more thing to do - whilst drinking your champagne on take-off, switch on the tail-mounted camera - I love the perspective on this. Beats the normal forward camera by miles.
