Mosquitoes are being eradicated on the island, but there are still quite a few of them. In the hotels, the rooms or beds are equipped with mosquito nets and some use mosquito repellent in the evening. It may be a good idea to take a mosquito repellent body spray with you.

Power outages occur quite frequently on the island. The network was built decades ago, and it is difficult for it to cope with the increasing use. Most hotels are prepared for this and switch to a generator. However, you may also want to carry a power bank, which can be a solution for temporary charging difficulties.
