Alton Towers has reduced the opening times of the Halloween Scarefest event by two hours across a third of its 16 nights.
Days between 21 and 25 October have been cut by two hours, with the park closing at 7pm.
Scarefest’s initial opening day of Friday 18 October has also been scrapped, being replaced by a standard 5pm theme park closure day.
Other nights of the 16-day event remain as 9pm closes, as has traditionally been the closing time for all nights of the event.
It means that dusk will be setting in just as the park closes during the 7pm dates, which are before the end of British Summer Time and the clocks going back one hour.
Alton Towers was widely expected to be considering the future form of Scarefest when it launched a guest survey relating to the event on its website last week.
Dependent on the falling of the October half-term holidays, the adjacent term-time week of Scarefest has traditional seen minimal queues for rides and attractions.
The park typically advises that its opening hours are subject to change, and bosses have previously reversed cuts to opening hours following negative feedback from customers.
Meanwhile, the Alton Towers will charge for its showcase scare maze Terror of the Towers after more than a decade of inclusive entry for visitors to theme park.
The returning Sanctuary scare maze will remain a paid attraction, with the Carnival of Screams becoming the new inclusive maze.
