Ive not used it yet, but will be in september. Ive had differing info on this, I work for disney here in the Uk, so called them, apprently all international arrivals have to collect their own luggage off the first and second carousel, and take it to the ME desk situated on the first floor.
BUT
on the internet it states that disney will collect it for you.
hopefully somebody will come along soon and clarify this
