Alton Towers recorded a 76% drop in profits during the 2011 season, recently-filed accounts show.
The resort, which operates as a division within operating group Merlin Entertainments, recorded pre-tax profits of £1.13 million.
2011 was the first year in recent memory that the park featured no new rides or attractions, with 2010 and the opening of the Thirteen rollercoaster generating £4.8 million in profits.
This year has seen a number of operational cutbacks at the park, including a reduction in park opening hours.
The SW7 rollercoaster, which will open next year, is reported to be costing between a 18 and 20 million pounds.
