I can say that about 90% of my visits have been either positive or at least neutral. If it's neutral it's usually somebody that doesn't talk but then I can just catch bugs/fish instead. A few good experiences include multiple tours with people that went really well, meeting people who have very nice towns, finding people with good crack(conversation) late at night whether it be nonsense or considering existence. Bad experiences which recently especially has been rare include stupid kids digging holes all over the island, kids chopping down all the trees just 'cos, being pressured by twelve year olds to "marry them" who then turn their wifi off when you say no, and of course the beggars who seem to think you owe them something.
