Spanish hoteliers are worried that the number of guests from the United Kingdom, the sector’s biggest source market, will suffer a major decline if London and Brussels fail to agree on a negotiated exit for the United Kingdom from the European Union.

“If there is a hard Brexit and all that entails, such as visas being required for British visitors or (there being) a big drop in the value of the British pound, we could see a 15% fall in the number of visitors compared with last year,” said Joan Molas, president, Confederation of Spanish Hotels & Tourist Accommodation.
