In reply to Kid Spatula:
Yeah, I've just checked... The passport includes all lifts bar one (Metro Alpine).

If you intend to use the Metro Alpine (ie Climb Allalinhorn or Alphubel) you will need to pay the extra 5sfr a day for the Saas-pass. It's unclear if you can wangle it such that you only pay the extra on the days you need to use the Metro Alpine but even if not the complete cost of unlimited up/down lift (and valley buses) is still great value.
