Beautiful Sentosa Island Excursion - Singapore Holidays. A day trip to this island is strongly recommended if you are visiting Singapore. It is one of those 'fun' places providing a meaningful difference in terms of attractions, which includes Madamme Tussaud, Universal Studios, Cable Cars, Merlion and lots of other attractions and shows, all on one island. It is a major tourist attraction, with hotels on the island too. There are lots of hawker stalls, restaurants and drink stalls all over. Great place for swimming at the beaches.
