How to kick out a neighbor without the need amibo Or to advance the day in the swich?

I imagine that to invite a camper it would be with amibo or that was the campaign thing and if it is the campaign thing, do we know how often they come?

Oh when you've saved and ended game you need to press 'home' then 'X' to quit out of AC before altering date/ time

No ive never noticed a set pattern to campers arriving at my campsite.. but I've never thought to note the frequency.. I dont have Amibos. So never invited one

If u get a camper in your campsite that u want to keep you have to talk to them a lot and win card games, eventually they will ask to stay and suggest a villager who will leave.

There is also the factor of the amount of villagers you already have. It's worth looking it up.. on nookepedia or somewhere to explain it better
