So, how does the campsite work fully?

[Wigan06]

So I've just built the campsite and I love the idea of seeing a new villager each day and being able to move a 10th one in but I was thinking what would happen if my 2nd favourite villager was in the campsite so I moved him in then it filled up my 10 slots then the next day, my favourite villager appeared. Would I be doomed to spend only that day with him and watch him disappear the next? Or is there some way around this? If not, it might cause more pain than happiness haha!

You can't have a camper move in when your village is already full.
