Hi Denise,
Disney is offering the greatest all-nighter ever! I wish had this type of all-nighter with no tests the next day!
The
Three-Park All-Nighter starts at 6:00 am on May 24 and finishes at 6:00 am on May 25. Only Magic Kingdom is open for the late night to 6:00 am on May 25.
You will only be charged one days admission to the park for May 24. So if you go to any park on May 24 and end up back at Magic Kingdom after midnight through 6:00 am, your
park hopper will not be charged for another day. However, if you went to another park later on May 25, you would be charged one days admission.
Since you
do not have a park hopper, your only option is to visit Magic Kingdom on May 24/25. You can always leave and come back with the older children but you could not go to any other major park on May 24 and then enter Magic Kingdom later. You would lose a day for that.
Wishing you a magical vacation!
Beth
