If you're talking about when you use a new character to choose where your new villager's plot will be.. Then yes, you can do this for the campsite.. People talk a bit about "Campsite resetting" on these forums, and that's essentially what that is
Just do be aware it gets very boring after a while :L
If you are gonna do it, try and do it between the months of May and August, because that's when I personally have found the most campers.. And I am speaking from experience as I've TT'd through over 5 years day-by-day and plot resetted new villagers and that's when I've found the most campers popping up
