How I spent my Holidays
I spent my holidays in Singapore.
I stayed with my family in a apartment at a skyscraper. We hade a really nice view of this big city. I can see for example the Marina Bay Sands. Which is on of the highest buildings in Singapore. There are many things to enjoy in Singapore. My family and I went to the harbours and we saw hundreds of ships. We enjoyed the boat rides and visited some of the islands near Singapore, which is the turtle Island. We also visited the Jurong Bird Park and the Botanical Garden. At night we was by the markets where we has eating. We were only 3 Days in Singapore. After this stop we fly to Phuket. This is a tourist Jsland by Thailand. There I have only relaxed at the Beach and I was diving by the coral reef.
