Thank you for your interest in Rio Grande Games.

You are nearly correct on the rules for Nobles. At the beginning of the second paragraph, the rules state, "Players can place nobles anywhere and anytime they would place colonists." In a game using the nobles expansion, there is always one noble on the Colonist ship, until they run out. When Mayor is taken, the person who takes that Noble can send them to any building they want, or to San Juan. The noble will function exactly as a colonist does when it occupies a building, unless the building lists different functions if occupied by noble or colonist. In addition, during the Mayor phase, when you can freely move colonists, you can also freely move nobles. However, when it is not Mayor phase, you may not move nobles, unless you are using the Guesthouse. If you have a noble staying in the Guesthouse, you can send it to a building as soon as you build it. Otherwise, you must wait until the Mayor phase to move your nobles around.
