Overall the experience was good. First flight of 17 hours had no entertainment since Singapore airline has technical issues. Was informed that passengers would get a $350 voucher for future flight. Uncertain how that is being distributed but would like to understand if an email is required from my end or if it is an automatic email sent to me by Singapore Airlines. -Gina Robles

What is good to know if travelling to Koh Samui?- Fisherman’s Village is packed with restaurants, shops, market stalls and bars. There is an Irish bar, naturally, called The Irish Times. The Billabong Surf Club flies the Aussie flag.
- Hua Thanon is a Muslim village on the south coast. While there are some restaurants and a wonderful beach, seeing the fishermen at work and looking at their beautifully decorated boats is the best thing.
- The bonus to playing a round of golf on Koh Samui are the beautiful views. The Santiburu Samui Country Club on the north coast is an 18-hole, par-72 course. The Royal Samui Golf and Country Club is located next to Chaweng Beach and will be an 18-hole course. It’s nine holes at present. There are views of Lamai, Cheweng and the surrounding islands.
- Samui Shooting Sport is close to Chaweng about 200 metres from the Tesco Lotus superstore. It’s a great place to let off some steam with, perhaps, an AK-47. Elephant trekking is a gentler option. It’s a great, slow, way to go into Koh Samaui’s jungly heart.
- From the pier at Bophut beach you can take a boat to Ko Pha Ngan or take a day trip to the Ang Thong National Marine Park, which consists of 42 limestone islands with soaring mountains, sheer cliffs and dense, green forest.
- Hin Ta and Hin Yai – Grandfather Rock and Grandmother Rock – provide a quirky photo op. The rocks, south of Chaweng beach, are shaped, suggestively, like male and female genitalia.
- The Muay Thai stadium in Chaweng town is worth a visit to experience this traditional sport.
