Yes, Singapore is clearly one of my favourite trips as huge part of my family live there. In this very modern and secure city country, you can visit the famous Sentosa Island, Universal Studio, Singapore Botanic Garden (free and amazingly big), Singapore zoo, Changi beach (less crowded but very beautiful and blue), Chinese + Japanese garden and its Turtle Museum.
And, if you love shopping, the Orchard Road is the symbol of modern European road and full of shopping centers. Additionally, you can also visit Bugis Junction for shopping. Enjoy it! 🙂
