How would I lerp or interpolate camera from one part to the second part in a loop?

I've been trying to make a camera move from one part to second part and then back to one part to the second part and so on in a loop. I've been using :Interpolate within a loop, but that doesn't seem to be working. Here is the code anyways.

local Player = game.Players.LocalPlayer

repeat wait() until Player.Character

local camera = game.Workspace.CurrentCamera
camera.CameraType = Enum.CameraType.Scriptable

local PosOne = game.Workspace.CameraA.CFrame
local FocusOne = game.Workspace.CameraA.CFrame + game.Workspace.CameraA.CFrame.lookVector
local PosTwo = game.Workspace.CameraB.CFrame
local FocusTwo = game.Workspace.CameraB.CFrame + game.Workspace.CameraB.CFrame.lookVector

camera.CFrame = game.Workspace.CameraA.CFrame
while true do
	camera:Interpolate(
		PosTwo,
		FocusTwo,
		5
	)
	wait()
	camera:Interpolate(
		PosOne,
		FocusOne,
		5
	)
end

Do you guys got better suggestions? Should I use :Lerp instead of :Interpolate? How would I do it in a loop? Thanks!
