Merlin Entertainments (LON:MERL) said its troubled Alton Towers theme Park was recovering as it forecast annual results in line with targets.
Merlin said trading at the Staffordshire attraction, where a serious accident occurred in June, had stayed significantly below the previous year.
But year-on-year declines had narrowed in the last few weeks, which the group attributed to a pick-up during Halloween.
Halloween also boosted like-for-like revenue in the group's Legoland Parks.
But Midway Attractions like-for-like revenue had continued to increase at lower levels amid ongoing challenging markets in London and Hong Kong, partly offset by strong performances in the rest of Asia.
The group said new attractions and accommodation opened this year, and in 2014, were still doing well and the broader new business development outlook stayed positive.
A Merlin spokesman said: "Whilst some significant trading days remain, including peak season trading for our attractions in Australia and New Zealand, Merlin expects to report full year results in line with current expectations, with underlying profit before tax broadly in line with the 2014 result."
Keith Bowman at Hargreaves Lansdown said: "In all, and given the success of rival Disney, Merlin remains firmly on the radar for investors.
"Growth prospects in China have recently been boosted via a joint venture to develop a LEGOLAND Park in the Shanghai area, whilst the group’s strategy of turning Parks into resorts with the opening of new hotels remains ongoing.
"For now and despite the Alton Towers accident, analyst consensus opinion remains highly favourable in tone, pointing towards a strong buy."
