If you do 2AK, depending on your "statures" you could dine together in the buddy seat and chat that way. Many warn it is cramped, however. There are many that don't like 4EF because it's open. Finally, I patiently read through the original threads (it will take you a fair amt of time) as the great insight will serve you well when making your decision. I ultimately stuck with 2AK for my mum's and my upcoming trip. Will be watching for 1AK to open up as we approach T-72. Enjoy the trip!
