Setting up a local network without internet connection?

Hi all!

I am going on vacation tomorrow, and i would like to play Minecraft with my family, but we don't have internet access. So i was wonering if it was possible to set up a local network connection between 2 or more computers without having access to the internet?  

Thank you in advance!

Yeah, Get an ethernet switch or just use your router if it has enough ports, hook them all up to it. Run a server off one computer and all the others can connect to the local IP.

Thanks :D This just saved our vacation ;)
