A lot of questions can be found here.

My spouse and I both play SOE games. Should we list one of us as a guest?
No. A guest is someone that does not play or have a subscription to any of the SOE online games. Each player should register individually to get his or her personalized Player Passport.

My spouse does not play SOE games but wants to come with me. What is the fee for someone that does not play?
The fee is the same for players and non-players. Just list them as your guest on the registration form.
