For character meals, Disney appears to be sticking with having them inside the theme parks or at resorts within walking or monorail distance of theme parks. Some of the outlying resorts used to have character meals but they were done away with.
There's also only one restaurant at DTD that is operated by Disney, so if they were to have a character meal anywhere else, they'd have to have some sort of third party agreement like they no doubt have for Disney characters to appear at the Regal Sun (Tuesdays, Thursdays and Saturdays for breakfast) and the Swan (nightly character dinner, character breakfast on weekends).
