i really like Marina Bay CBD area and i also miss Tanjong Pagar where i used to stay at the Duxton Hotel. you can also do another walking resembling the F1 track around Marina Bay like Republic and Raffles Boulevards, Nicoll Highway, Stamford Road, St. Andrews Road (Padang and Civic District), Anderson Bridge, Esplanade Bridge, Raffles Avenue and finally the pit straight next to the Singapore Flyer. you may even want to enter the floating stadium most probably for the final time prior to the NS Square redevelopment.
