We advise to check the amount of traffic included, even though plenty yachts now offer unlimited internet. Have in mind that some remote islands in Croatia can have limited access to internet.
Almost all of them are. You might find some older traditional ships that don’t have AC or have it in saloon only. What you need to have in mind is that some yachts have certain number of hours of air condition daily included in charter prices. Anything above that could be charged extra as extra generator work.
