Looks like SDL will be using the old Fast Pass system. The Fast Pass machines will be located in rather large clusters and service all the rides in the area, like how New Fantaslyland Fast Passes worked before My Magic +.
Also, looks like SDL take a hand out of DHS's book and have a dance party as an attraction. It is in Tomorrowland and named Club Destin-E.
On a more positive note, the Treasure Cove area will have a pirate themed stunt show called Eye of the Storm. That may have already been stated, idk.
