how to add area teleporter?

This script teleports everyone in the server to a certain spot no matter where they are. how would i change it so that it only teleports people from a certain area?

local status = game.ReplicatedStorage.status
local maps = game.ReplicatedStorage.maps:GetChildren()
while true do
    for i = 1,59 do
        status.Value = "Intermisson:"..59-i
        wait(1)
    end

    local rand = math.random(1, #maps)

    local map = maps [rand]:Clone()
    map.Parent = workspace

    status.Value = "we'll be playing "..map.Name
    wait(4)

    local players = game.Players:GetChildren()
    for i = 1,#players do
        if players[i].Character ~= nil then
            local spawnLocation = math.random(1,#workspace.Teleports:GetChildren())
            players.[i].Character:MoveTo(workspace.Teleports:GetChildren()[spawnLocation].Position)
            players.[i].Character.Parent = workspace.ingame
        end
    end

    local roundlength = 50
    local canwin = true

    if map:FindFirstChild("obby") then
        map.endpart.Touched:Connect(function(hit)
            if hit.Parent:FindFirstChild("Humanoid")then
                canwin = false
                status.value = hit.Parent.name.."he's won"
            end
        end)
    end

    repeat
        roundlength = roundlength -1
        status.Value =  "time left:"..roundlength
        wait(1)
    until roundlength == 0 or canwin == false or #workspace.ingame:GetChildren()==0

    wait(3)
    map: destroy()

    local players = game.Players:GetChildren()
    for i = 1, #players do
        if players[i].Character ~= nil then
            players[i]:LoadCharacter()
        end
        end
    end
