Of course you can - the balcony bar is THE feature that makes SIN the number one airport in my books. After hours of flight you can finally go outside to sit among plants, have a beer, enjoy the weather and fresh air (as fresh as can be in the middle of an airport) and have a smoke too!
Without that feature, it would be one among many airports..
We flew via Singapore airport to New Zealand from Manchester, and I can honestly say that the best thing about it was the windowless airport hotel room where we got a few hours shut-eye.
I remember it being a great airport and of course I love Singapore. I have eaten some of the best food that I have ever eaten there. We flew with Singapore Air on A380 to Sydney via Singapore and had a excellent journey. On the way back we sat upstairs as there also economy seats there. The great thing is that there are 2 seats rather 3 seats which means if there are two of you travelling no one has to get the crap middle seat.
I enjoyed the flight and watched loads of films. I don't remember there being any problems with collecting our baggage.
If you want to see which seats are good or bad on a plane then have a look at www.seatguru.com
There used to be a public swimming pool on the roof, is it still there?
I lived in Penang Malaysia for 3 years, and much later I spent 9 weeks working in Singapore. I feel sorry for the natives, I didn't find it a very nice place at all.
Best business class experience EVAAAAAR!!! And now thinking back to my last flight from CDG where I had to stand in line for 30 minutes just to drop my luggage in business :P
