I was at a Ghost Train behind the scenes tour last Tuesday with the initial presentation taking place in the hospitality tent thing - Fright Nights rehearsals were taking place next door and they were definitely rehearsing to the Big Top theme which I believe is used in the Big Top room in Trailers, so that seems to suggest it'll return this year.
Hoping that the scenes that remain inside Trailers are modified in some way too - Trailers was really showing signs of aging last year and was looking really, really exhausted.
