Thanks for the replies. Ended up picking CDG to experience the 777-300ER F suites. Hopefully the 12 hour in flight experience will make up for the 2 hours spent in CDG before our return flight to the US.

One question - for 2 people traveling together, what are the best F seats on the 777-300ER? If the middle two, can the divider be lowered so we can see/talk to one another?
