Other than flipping a coin you have to chose what you like. Beach comber, boating, small buildings, smaller more private pools, big spread out resort chose CBR. If you like the old southern charm, smaller resort, big buildings (it's a lot like New Orleans but the buildings are freshly painted and the trash gets picked up every day) then chose Port Orleans French Quarter.
We have stayed at both resorts. We loved both resorts. The girls wanted to back to CBR, I would have chosen POFQ. I was out voted but that's ok because both resorts are great. You can't lose!
