I'm making a party system and i dont know where to start?

Okay so I'm making a party system and I want it so when the party leader gets teleported everyone else in the party gets teleported this is an rpg type game with portals that teleports you to a different place like the teleport system

I really dont know where to start how would i cast the array through all the players when theyre object values

heres the party script

game.Players.PlayerAdded:Connect(function(player)
	local PartyFolder = Instance.new("Folder",player)
	PartyFolder.Name = "Party"
	local User = Instance.new("ObjectValue",PartyFolder)
	User.Name = player.Name
	User.Value = player
	print(User.Value)
end)

I'm sure we've all gotten stuck on something similar. The answer is to use a for i,v in pairs loop. Like so:

for i,v in pairs(PartyFolder:GetChildren()) do
	local player = v.Value
	-- do stuff to player
end
