Question regarding reserved servers?

Before asking my question i shall give some background. I am making a Death run. I made the maps in different worlds. I can successfully teleport them to the world, but my concern was about others joining an ongoing game. I looked into reserved servers and was going to test it out. I don't have enough people to test it out, and I'm not quite sure if my computer can run a bunch of test players. If I just use the first example here (without the message part, just teleport everyone) - https://developer.roblox.com/api-reference/function/TeleportService/ReserveServer -will it teleport another batch of people to the same server later.
