Each seat is a 4 foot long by 30 inch deep spot. The tables sit two attendees and are 8 foot by 30 inch deep. You may place your machine on the floor or table.
If you need the extra real estate you can buy two seats together to run your triple monitor setup. Otherwise you are restricted to the normal seat size.
Bring a network cord just in case but each spot will be provided a network run.
We also try to provide surge protectors that are set up and ready for you to plug into but bringing an extension cord/long power wires are a good idea.
