How does Saturday the 18th sound? There are no evening EMH hours that I could see. Gives everyone a chance to enjoy the parks into the evening then head to Riverside for YHB. Hopefully enough people are still around post cruise to make this worth while.
Closings: AK-6pm, DHS-8pm, Epcot-9:30pm, MK-10pm
YHB goes until midnight / 12:30am
If this has legs I'll make it official.
