My husband and I love CityWalk. Not only is it closer to where we live, we like the restaurants better, and the $7.25 evening movie price with my pass is a great deal. We rarely see movies anywhere else.
DD seems more touristy, CW feels much more local, and people actually dress up to go clubbing. And no, we don't go in the clubs, we just like to eat there, listen to live music when it's there, sometimes take a boat to one of the hotels, and soak in the atmosphere. I have never really noticed it attracting that bad of a crowd.
