That doesn't tell the whole story, though. The new additions to the
DDP 2-credit list (e.g., Akershus L/D, Cinderella's Royal Table, Storybook Dining at Artist Point, etc.), as well as some of the old 2-credit spots (e.g., Hoop-dee-Doo Revue, Be Our Guest, Le Cellier, Brown Derby, and room service orders) may not appear on that list, but will still be 2 credits on the DDP. (Interestingly, California Grill and STK, formerly 2-credit restaurants, don't turn up in the Fine/Signature Dining/DDP results at all. Either they're not participating in the DDP this year, or they haven't committed yet. Space 220, Chefs de France, and Monsieur Paul aren't listed as 2024 DDP participants at this juncture either, but they'd all be expected to be 2-credit experiences as well.)
