We've stayed at both resorts and while I like them both, If I had young children I would pick POR. CBR is a very large resort - from many buildings you need to take an internal bus to get to the food court/main pool area. While you can request the buildings close to this area - Martinique, Trinidad North - requests aren't always honored. I was lucky and got my request of Trinidad North, which was right next to the food court. I saw many people in the morning coming from the internal bus to pick up food and coffee. Just my opinion - I wouldn't want to deal with this with younger children. But they are both beautiful resorts.
