Does URComped always link a player's account to their spouses?

No! This is optional. URComped does not require you to link accounts between guests. After your first trip, you will have the opportunity to link your account with your guest. You should link your account only with someone who travels with you all the time. If you do want to link accounts, please let your URComped host know and all your offers going forward will be based on your combined play!
