When should I arrive?
You should arrive at the table where they are selling entries about 20 minutes early for the event you want to enter. Allow a little time to get oriented the first time. Finding your way around can be confusing.
Where is the Newcomer area?
There will be a special area for the Intermediate/Newcomer games. Ask a director or someone at the hospitality desk where the I/N area is. When you pay your entry fee tell the person at the desk how many Master Points you have and they will put you in the right strata.
I'm a little nervous.
Playing in a tournament can be a little intimidating the first time, but there is nothing to be worried about. You will find the people friendly (we all remember OUR first time at a tournament) and you will be playing with people at your same level of experience.
