Does this Map Changer Work?

while true do
game.Lighting.Map1:clone().Parent = game.Workspace
wait(120)
game.Workspace.Map1:remove()
wait()

end

I believe I did it right!

It doe work congratulations! Using server storage would be better although, server storage actually stores models and guis into it and be copied right out of it into a new parent like you did!

If you want to have multiple maps, I recommend doing

for i,v in pairs(game.Workspace.ModelWhereTheMapGoes:GetChildren()) do -- creates a table (list) of everything inside the model, then removes everything in it.
v:Destroy()
end
game.ServerStorage.MapYouWantToAddToWorkspace:Clone().Parent=game.Workspace.ModelWhereTheMapGoes
