One does not travel to Singapore and not visit the famous Marina Bay Sands Hotel. Hopefully one gets to stay there to experience the hotel, in particular, the infinity pool as this is the only way you will get to swim in it, or even get close to the pool unless you're a staying guest. This actually works in favour of guests as there are so many people visiting the famous hotel. There are bars and a few restaurants at the top, as well as an observatory deck all open to the general public.
