It is sometimes hard to find these basic things even in a big city, and Mekong Delta is by no means a big city. If your tour is tailored by the likes of Mekong Kingdoms, your needs will be taken care of, but should there be an emergency, you need to have these essentials with you - soap, shampoo and feminine hygiene products are a must, you'll also need to bring an extra deodorant stick: you don't want to run out of deodorant in this humid weather, and you can count on that. Also, pack pain relievers and antihistamines – the weather could give you headaches and allergies even if you are not prone to them. What's more; you don't need makeup at all apart from sunscreen and a lip balm with SPF – your makeup is going to melt on your face the moment you are out of your air-conditioned cabin.
