ourists from the Continent are flocking to the firm's London attractions which include Madame Tussauds.
The firm said it entered 2017 in a strong position after posting a 3.4 per cent rise in 2016 pre-tax profit.
"Trading at this seasonally quiet point in the year is in line with expectations, with planned investments and new developments on track," it said.
"We are encouraged by recent trends in European visitation to our London attractions as the more competitive exchange rate begins to impact holiday decisions."
The world's second-biggest visitor attractions group behind Walt Disney said it would remain alert to geo-political uncertainties after militant attacks in Europe last year deterred tourists from visiting major sites.
Merlin said it made a pre-tax profit of £277m compared with analysts' average forecast of £273m and the £250m made in 2015.
"Whilst we are planning prudently, we remain confident of a good performance in the year ahead," it said.
