Tough trading at city centre attractions such as Madame Tussauds took the shine off higher revenue at theme park operator Merlin Entertainments plc (LON:MERL).
Merlin, which was fined £5mln this week for an accident at Alton Towers last year, said like-for-like revenue in the 38 weeks to September 17 rose 1.3%.
Revenue on an actual currency basis increased 10.6% as a result of a positive effect from translating international non-sterling revenue, due to the lower pound.
The group also reported a strong performance in its Legoland parks business and evidence of a recovery in its theme parks.
But Merlin said trading in its Midway Attractions arm, which includes venues such as Madame Tussauds, the London Eye and Sea Life, stayed difficult in a number of key markets.
It blamed wider security concerns for volatile trading at Midway, particularly Midway London which has failed to see any significant boost to visitor numbers from the weakness of sterling.
"The cluster's 'Eye-Popping Days Out' marketing campaign over the summer, specifically targeting the domestic market, did however arrest the decline in August," it said.
It added that the roll-out of new Midway attractions continues to make a significant contribution to overall operating group revenue growth.
Four attractions opened in the year to date, each with positive guest feedback and encouraging early trading.
"We remain confident in our 2020 strategic milestone of 40 new attractions," it said.
Merlin received a £5mln fine and £69,000 costs for breaching the Health and Safety at Work Act related to 'The Smiler' incident at Alton Towers in June 2015, in which five people were seriously injured.
Chief executive Nick Varney said: "From the beginning the company has accepted full responsibility for the accident and strived to support all those injured in every way possible.
"We have learned every lesson from what happened last year and made a number of technical and procedural improvements to ensure an accident like this cannot happen again."
