Do New Guest bonuses trigger again when the guest is played later, and how do Bards work?

Question

Accepted Answer

Not for New Guests: the Reputation or Schnapps bonus on such a guest is earned only when you recruit it, not when you seat it later. Bards work differently: each Bard drawn in Phase B lets you move 1 space on the Reputation Track in Phase F.
