Do not bring too much baggage.
  1. 3 swimsuits is enough to bring
  2. Shorts and lightweight pants
  3. 2 pairs of slippers would be fine (flip flops)
  4. Don't forget to bring a basic first aid kit
  5. Sunblock, mosquito spray and aftersun are all available on the island.

Some other tips to consider:

It's much nicer to swim in the morning, when it is much more peaceful.

It's nice to take a nap around 1 to 3pm for you to prepare your nightlife escapade.

Try to experience island hopping.
