HSLD,
Our MD's don't fly to Narita unless we're on fire or out of coffee.
My favorite since working at UPS of course is Hong Kong. I have been nominated and gracefully accepted the title(s) of:
"King of Kong" and "Mayor of Sticky Fingers"...both are unlimited in duration with limited tax perks.
On the MD11, we fly to Honolulu (HNL) which is a top layover for me. At sunset you start at Duke's, then pub crawl to Moose's, Tsunami, and then the bar across the street, then the weird one on the 2nd story, then finish by going to Jack in the Box (sorry my memory isn't the sharpest by this time of night and after the pub crawl).
But really, a layover is what you make of it and who you're hanging with.
Here's my short list a fav layovers:
HNL, Frankfurt, Vegas, HKG, London (Gatwick/Stansted), Cairo, Tel Aviv, St. Louis, and the Shang (Shanghai)....and anywhere else that I can get really drunk and ride the city bus around and annoy people. (Q10 bus at Kew Gardens in Queens).
