Getting to the race track from Gardens by the Bay wasn’t hard, but there was a bit of walking to the closest MRT station, through the Marina Bay Sands. We jumped on a train for a couple of stops, and then changed to another train. On the platform helpful people were explaining that there were a few different trains going to different places on the same platform, we had to wait a whole extra 2min. Getting out the station and into the track was a lot easier than navigating 3 shopping centres from where the busses all stopped.
The good thing about the Singapore Grand Prix being run in the evening is that there is no rush to get up and head out first thing in the morning. The most urgent thing before lunch is making sure you get to the hotel breakfast before they stop serving.
It also means when you do eventually head out at a reasonable hour you have time to do tourist things before heading into the Grand Prix.
The last time I was in Singapore was just a few months ago, after my 6 weeks in Europe. I had planned to do a few things in Singapore on the way through back to Australia but I ended up spending most of the time in my hotel room after eating a dodgy bread and butter pudding and getting some nasty food poisoning – this trip was much more enjoyable.
We walked down the street to the bus stop and caught a local bus into town. For S$20 (AUD$15) (plus S$10 deposits) tourist can get unlimited travel on the trains and busses in Singapore for 3 days, not a bad deal the trains are clean, quiet and efficient. There is never a reason to run for a train, there will be another one in just a few minutes.
