All the islands I've gone to have been horrible honestly. They all have cherries my town fruit. 90 percent have pansies my town flower and no resident at all. I was getting really annoyed after my 6th island of just samey stuff. I got bamboo. That was the only highlight
I will try one last time
There seems to be 'tiers' of islands, the more common ones will normally have your fruit and flower, the uncommon ones will have different fruit and/or flowers, and the rare ones are all over the place in what they have.
I loved my islands. First one was uneventful - there were a few cosmos, same orange trees. Next few islands are fun - one was a bamboo island, another was a cherry island. I got Big Top, Audie (yay!!) and Molly (she's adorable!!). Gonna island hop some more today!
