Which now? They are both pretty big, but DPC is bigger and less 'pedestrian friendly' if you want to put it that way. All of the buildings on the left side (as you are looking at the ocean) are accessable only by bridges over the pool area, no walkways at all on that side. Oh, and when they say swim out rooms, they don't actually swim out. There is an offshoot of the pool that goes between 2 buildings but they don't go right to the rooms. The great thing about OB is that there is a shuttle that goes around the resort in a loop. So after a long day, it's nice to just jump on the trolly and they will take you where you need to get to. Let me know if you have any questions about either resort!
