We were able to walk into to Storyteller's on many occasions with no problems. Blue Bayou, Cafe Orleans and Carnation Cafe are the only places in DL that we have been turned away from and it's happened the most at BB. In DCA we were turned away from Ariel's Grotto once but I imagine with the WoC preferred dining packages it's a little harder to walk into AG and perhaps even WCT, you may want to keep that in mind.

Of course the times we were turned away from BB we walked away, called the dining line and made a ressie for the following day so that's always an option as well.

Not guaranteed but an option.
