Hi there,
This year Halloween Festival will take place from Oct. 1st to 31st.
Actually, children can dress up and/or be disguised the way they wish as far as it is Disney related... During Halloween period, Frontierland becomes Halloweenland and there are stands where children can get face painting and things like that (note that lines & wait times can be important) especially during school holidays.
Some adults are wearing sometimes a halloween hat or specific merchandise but not so much adult guests come in the game.
By the way (sorry to "break the magic"), except on
MNSSHP or Halloween party, adults are not allowed to wear costumes for misc. reasons.
The only thing which remains impossible : to wear a mask & beeing dressed like a real Disney character. And faces must be seen at all times.
More specificaly MNSSHP 2011 dates are : 7th, 14th, 21st & 28th October 2011. Entrance fee ; £ 23 per person (free under 3 years old)
Feel free to ask if you need to...
