Here's how EMH works for all parks.
Look up the POSTED open and close times for any day, any park.
Only WDW resort guests staying on-property will be allowed EHM privileges and it COSTS NOTHING EXTRA to attend the EMHs.
There are slightly different situations for MORNING and EVENING EMH's.
-------MORNING EMH FACTS--------------------------------------
If it is a MORNING EMH, then WDW resort guests staying on-property will be allowed entry to THAT park on THAT day starting ONE HOUR before the posted opening time.
At least ONE person in your party should have a room key-card with them (sometimes EACH person needs to show one) to verify your current hotel status and gain entry.
So, only WDW resort guests will be ALLOWED INTO the park.
Once inside, only selected attractions will be open.
See the official WDW website for the latest attractions that will be open during EMH.

-------EVENING EMH FACTS--------------------------------------
If it is a EVENING EMH, then WDW resort guests staying on-property will be allowed to stay and ride attractions at THAT park on THAT day for THREE HOURS after the posted closing time.
You do NOT have to be in the park BEFORE scheduled closing time.
You CAN enter the park at any time during EMH and still get a wrist-band.
You can leave and re-enter the park at will (just like any normal time).
(So, YES, if MK is sched. to close at midnight, the EMH will run til 3AM! Yep, that's 3 in the morning. No, its not a mistake, that would be 3 full hours after the posted time. 3AM for a posted 12mid close-time. 3AM, yes sir!)
EACH guest (except for very small children) will need to show a room key-card to a CM at special "EMH kiosks" set up in various locations throughout the park, and a wristband will be snapped on by the CM to each adult and child. Children older the 3 will be issued a room key when you check in if they are listed on your ressie. If they are not listed you will have problems if they don't get issued a room key.Children older than 3 years will be issued a room key when you check in. Make SURE the check-in desk issues each one a room-card.
The ride CMs will check these at each attraction before allowing guests to enter the queue.
So, even though non-resort guests may still be INSIDE the park, only those with wrist-bands will be allowed to ride any open EMH attractions.

--------------------------------------------------------------------
You can enter the parks for EMH EVENINGS anytime... during "regular" hours, or even during the actual extended EMH hours.
This 1-hour morning EMH and 3-hour evening EMH rule applies at all 4 parks. Enjoy!
