No friends, worth buying?

I played this game offline for a bit on a simulator but really want to get the proper version for my switch 1 as the offline version is very limited with only being able to visit one isle. Absolutely love the laid back way to play and all the possibilities. ☺️

I don't have any friends though and after reading I cant just visit random islands I am not sure if I should buy it?

Is there a discord server to find regular people to play with or any other way?
