How to make a teleport after an event?

Teleport script

if game.Workspace.Bool.Value == true then
    local g = {game.Players:GetChildren()}
    for i = 1, #g do
        g[i].Character:Moveto(Vector3.new(0,0,0))
    end
end

GUI script

time = 20

if game.Players.NumPlayers >= 1 then
    script.Parent.Text = "Pick your team before times up"
    for i = 1, 20 do 
        wait(1)
        time = time - 1
        script.Parent.Text = "Round begins in: "..tostring(time)..""
    end
    script.Parent.Text = "Let the game begin"
    game.Workspace.Bool.Value = true
end

I have this countdown GUI and after it hits 0, it sets a BoolValue to true, and I want it to teleport all the people in one area to a certain part of the map and the rest of the people in a different area to a different part of the map
