I am stopping over in Singapore airport in between connecting flights. I only have 3 1/2 hours to spare.
I have heard about bus tours, etc but I dont know if I have enough time for any of that.
Can anyone tell me if I can do the bus tour or anything else that I can do?
I wouldn't bother with the bus tour, to be honest. 3.5 hours is a bit rushed, you won't get to see much anyway. Changi Airport has quite a range of activities for passengers in transit, so perhaps you'd like to check out this link:
You get a free bus tour if you have at least 6 hours between the connecting flights.
There is a nice swimming pool so stick with that if you want that holiday feeling..
I would just stay at Singapore airport if I was you. It's a massive airport so there's enough things to do for a few hours. Last time I was there they had free internet, free X-boxes to play on, loads of shops, free movies being shown and there was even a gameshow type quiz being hosted where passengers could enter a competition to win free flights.
Changi is like a whole city in an airport... so just stay there, don't bother going out... you might miss your flight with just 3.5 hours to spare if you go out of the airport...
