Having a portable Wi-Fi device will help you to easily navigate around the unknown streets of Malaysia. The same goes for exploring Langkawi. Plus, a portable Wi-Fi device will be useful for when you want to update your social media status or let your Instagram followers know how amazing the island and your Langkawi resort is.
A good camera is, of course, necessary for chronicling your magical adventure on Langkawi. Make sure to take along a dry bag too for storing your camera and other electronic devices when you are on the beach. Sand can cause irreversible damage to sensitive equipment.
Enjoy!
