The maps will be reset every 3 hours. Right now you should all spawn in Dewtropolis. But in case you don't use /spawn to get to where you need to go.
Dewtopia: /mvtp dewtopia
Outback: /mvtp outback
Protip: If you rename a Squid Spawn Egg to tnt then it will spawn a 3x3x3 block of TNT where you right click.
