My friends be going to disneyland Paris on 25th October to 31 October 2014 during the party on 31st October one friends be dress up as an ghost and be wearing an mask as part of the costume will she be allowed in the park with mask on.
The info from Disney regarding costumes and the Halloween Party:
"During normal park operating hours, costumes are only permitted for guests aged eleven and younger. Wearing a Halloween costume will be exceptionally allowed during the evening however Disney reserve the right to refuse entry to anyone wearing an outfit that is deemed offensive, shocking or dangerous. Guests that dress like Disney characters may not post for pictures or sign autographs for other guests."
Not sure on the mask situation though.
I posted this in another Halloween related thread not so long ago.
This is from the pamflet from last year.
