Why we chose the above places to visit:
Gardens by the Bay: many flowers from different countries, which suits the interest of the buddy.
Bukit Timah Hill Reserve: free of charge, not as much flower species there, but the buddy will be able to enjoy the scenery while admiring the flowers, so this would be an enjoyable and fun experience.
Nearby hawker centre: Cheap, and vegetarian food is available.
Singapore zoo: one of the best zoos in the world, and the buddy loves animals.
Bugis: A few malls available there, with Bugis street nearby which sells cheap souvenirs and items.
Why we did not choose jurong east and jurong bird park:
Jurong East: no sale of souvenirs, and items are pricey
Jurong bird park: expensive, and not as exciting as the Singapore Zoo
