Looking for some regular travellers such as @sbiddle to offer their experience's.
Ill be traveling across the ditch soon and both route segments will be on the 773. Im taking the significant other away for a combined birthday/anniversary and I was going to go all out with Business both ways (given the occasion) but now I'm considering the Premium Economy/Space Seats instead.
The Space Seats mean you will be seated together and if you take the centre aisle seats, they are advertised as been perfect couples because she can ever so conveniently place her legs over your lap while she sleeps and use all of your shared table. The business premier seating means you can't actually see each other, you would have to remove yourself from your seat to interact.
Question is, when travelling for only 3-4 hrs do you really want to talk and interact with your other half? Or would you actually prefer the luxury of having some 'me' time and privacy along with more premium facilities/seating & food?
