Creating a multiplayer player hub area?

[poettlr]

Hello,

I hope I'm in the right part of the forums, its my first post

I'm currently researching possibilities on creating a multiplayer hub area for my players. The basic idea is players connect and start in the hub (50+ players).
Here they should be able to do a couple of things like:

• Run around.
• Do Emotes
• Invite or be invited to a party
• Start a game session (4 players, p2p)

A player should be able to start a session alone or as a party-leader. Here comes the crutial part, the game is currently planned as a four player game without a dedicated server. I know I need a dedicated server for the hub. How would I go by implementing that in unreal? As far as I know my options are

• Connecting to the Hub Session
  • Establish all infos for a "session"
  • Disconnect from the hub and connect/host to the new session
• Use Online Beacons
  • I think?
• Self made tcp connection for the hub?

Can anyone give me some pointers to get me into the right direction and/or tell me if I missed something?

Thanks in advance!
Cheers;
