I can highly recommend "The Best Exotic Marigold Hotel", best taken reclined in your BA Club seat en route to India. This is was always going to be a strange trip, used to spending multiples of 3 months travelling round the country on a budget, this was a 4 day working trip on expenses in quality hotels and driven everywhere.
Still, it doesn't matter what airline and which class of service, it's always an exciting chaos that greats you at any Indian airport. Long queue for immigration but smiles at the desk, an hour to get priority bags to the conveyor and madness once through the exit. Driver was waiting at the funnel from airside to outside. The smells and sights on the transfer to the hotel, even at 5am, were classic India. Security was very tight at the Taj, it was only as I was drifting off to sleep a while later that I remembered how close to home security was for the Taj group.
