Disneyland Paris is under pricing investigation as it reportedly charges British tourists higher than French visitors.
The Financial Times reports that the theme park is being probed by the European Commission on its price rates as claims from British customers being charged differently from the locals continue to increase.
The Brits are paying £372 more than the French for premium packages. Visitors from the UK are reportedly charged for 1,870 euros (£1,327), and Germans are charged for 2,447 euros (£1,736). The theme park only charges 1,346 euros (£955) for French ticketholders.
FT added that foreigners pay 15% more for one-day tickets.
EU commissioner Elzbieta Bienkowska said the growing number of complaints are "very significant, particularly in one or two instances".
"It is time to get to the bottom of this," she said. "I am interested in answers and explanations. On the face of it, I struggle to see what objective justification there could be for these practices."
Although EU allows price differences among its member countries under certain conditions like seasonal demands, it doesn't encourage establishments to charge differently basing on the country the customer comes from.
Disneyland Paris stated that its price promotions are based on school holiday periods exclusively for its local markets and the said promotions are not offered to foreigners.
"When purchased directly with Disneyland Paris, the cost of a basic resort package - without promotional offers - is identical across all markets, give or take exchange rates," the company said.
"Throughout the year we try to attract guests from different markets by offering market-specific 'book-by' promotions that can include discounts. Those promotions take into consideration factors specific to people in the local market, such as their school holiday calendar and booking patterns."
The company suggests to contact its central reservation office to see if there are any promotional offers outside their local market "and request to make that specific booking."
