The Oberoi New Delhi is a property which we almost stumbled onto accidentally but ended up loving. The room hardware and public spaces are thoroughly modern and service is as good as any that I have encountered in any city hotel.
After a fantastic few hours spent enjoying the restaurant quality food and drink at the private First Class Terminal, we were guided through a private border post and had our bags loaded onto our Porsche transfer vehicle.
Superb room hardware and the game viewing was as private and wild as you could possibly hope for. For the majority of our time on the game drives, it felt like we were at one with nature, totally disconnected from other human beings and the outside world.
Singapore Business on the A380 is one of the very best products in the sky. The whalejet has huge side bins, wide aisles, less engine noise and notably better air quality than the 77W.
If you aren't in the mini-cabin on the 77W I'm sure you can make an argument for this being the better product.
I really enjoyed the Air Canada lounge. It did get busier as time wore on but was cleaned constantly and dishes were replenished well before they ran out. Also, the design made the space feel a lot less busy than it would have felt had the seats all been placed in unbroken rows - as tends to be the case in AA or BA lounges.
