However, he added that "Britain remains our most challenging market for the upcoming peak season.
"While we welcome the fact that visitor numbers are up 2.4% for January to April, we know that currency fluctuations and the Brexit extension will continue to cause uncertainty for the summer season and may affect travel demand."
