Thankfully the MiceChat family was able to let me know my desire to knock out Adventureland/NewOrleans Square on an EMH was undoable. Some further googling (although not terribly easy to find) gave me the following list of attractions available during EMH.
Fantasyland: Alice in Wonderland, Dumbo the Flying Elephant, King Arthur Carrousel, Mad Tea Party, Matterhorn Bobsleds, Mr. Toad's Wild Ride, Peter Pan's Flight, Pinocchio's Daring Journey, Snow White's Scary Adventure Tomorrowland: Buzz Lightyear Astro Blasters, Disneyland Monorail, Finding Nemo Submarine Voyage, Space Mountain
Are there any sort of restrictions for DCA during EMH? I didn't see any, but then again, I didn't know about the DL restrictions either.
Also, are you able to go all over DL, to the lands which aren't open? I realize the attractions wouldn't be running, but just exploring the empty park towards the end of EMH would be an awesome experience if possible... and poise us to hit those other E-ticket rides first minute they open....
