One thing I can reccomend is that if you’re up to the task it is very possible to get a commerical Nvidia graphics card and run two gaming VMs that can use the graphics card that they’ll be able to connect to with their laptops (if they have them). Might save two birds with one stone if you’re willing to be maintenance! Some videos on the topic here and here. I run this everyday and it works great for me. I will warn you though, Java Minecraft may not work. Idk if it’s just my setup, but the only game I can’t run on my server is Java Minecraft

Obvious biggest upside is they’ll be able to play games together :) I reccomend good WiFi and Ethernet cables they can plug in at a desk though because the Ethernet cables make things way smoother
