You can get into the park with your MNSSHP ticket starting around 4. Party actually starts around 7 and goes until midnight (although I think times may change depending on park hours on that particular day.)
Events consist of candy spots all over MK where you can trick or treat, many different areas for photo ops which are only available during MNSSHP. Character Meet and Greets, a lot of rare characters are out. Different dance parties in the different lands. The whole park is themed and lighted differently which really gives it a whole other feel. Hallowishes, which is a really awesome display of fireworks. The parade, which has the headless horseman as the grand marshal.
Oh yeah I forgot the best part. Very little wait time for most rides.
IMHO, yeah its worth getting a ticket. Most times I suggest tickets for two nights, one for the parties and candy. The other for riding all the rides you can.
Hope this helps.....if you have any other questions, let me know!! :wave:
