Travel insurance
Check whether your bank card or home insurance already covers this trip.
If the trip needs a visa, the travel agent or visa centre usually sells the cover it asks for.
Mobile data (eSIM)
Your own plan's EU roaming may already cover this.
Renting a pocket Wi-Fi is the other common way to stay connected.
These are sites people in book with. Each opens in a new tab, on the site's own pages.

Ten-year averages for this calendar month. A rainy day is one with at least 1 mm of rain, as a weather station counts it. The model these figures come from drizzles more than a rain gauge, the more so the warmer the month, so its days count from 2 mm, rising to 5 mm in the hottest.
Weather read at Kailua-Kona, 11 km from the airport (KOA): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.
