I had 1f and 2f combined to myself JFK-FRA and had a fantastic FA. Was fun to have work up on one screen and entertainment on the other while lounging on a double bed. Not sure I would have enjoyed it nearly as much in a single suite. The single bed seems like it would be real narrow and shoves you up against a wall. Food wasn’t as good as NH/JL imo but still quite good. It is indeed an insane amount of space to dedicate to one person - just wish they had utilized it more intelligently.
