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

We do not- it is OPTIONAL.

After your first trip, you will get an email (once we get your play data) stating that your play is now verified and ask if you like us to link accounts with your guest. Do not link your account with someone who doesn't always travel with you.

If you do want to link accounts, respond "Yes, I'd like to link our accounts." Going forward, your offers would be based on your combined play.
