The emirates have great hotels but the Marina Bay Sands is the best, access to the Skypark is about £12, cafe and restaurant on the viewing deck but only residents can use the pool.
Not nearly the highest building in the world but just higher than the others around so plenty to see unlike Dubai where the Burj dwarfs everything.
Quick sunset mooch then Tacos at The Customs House right on the bay before the evening show.
The bay is sizeable which shows off the buildings well plus gives plenty of room for all to enjoy. Rather than being cramped around the harbour beneath the Burj Khalifa. The gardens by the bay have a show at Supertree grove, that’s 2.
The MRT is a dream, every 5 minutes, clean and fast as you would expect. Key is, I have not had to stand once whereas although equally as good at another city I only sat once and twice was unable to alight as full.
A lot more than 2 lines as well.
Traveling and staying off the booze.
