We have an upcoming preferred room reservation at CBR, as well.
We've requested (via the online check-in menus) Martinique village. Preferred rooms in Martinique are in buildings 24, 25 and 26. Buses generally move clockwise around the resort beginning in Jamaica or Martinique, meaning Martinique will always get picked up/dropped off just before the busy Old Port Royale stop (with Trinidad North getting picked up right after Old Port Royale). Since we'll be relying on Disney bus transportation, we thought we'd rather opt for the village that would give us a better chance of getting a seat on the bus, before it becomes standing-room-only or fills up completely, even if it means spending a few more minutes on the bus when heading out to a park.
