We are just beginning to plan a trip to Portugal from October 27 to November 17 (2022). I have a request from one of the lodgings I booked through Booking.com to complete a form through app.talkguest.com. It asks for information such as name, date of birth and passport number.
Only one accomodation has requested this information and I have not been asked in the past in other EU countries to complete this.
Is this a process specific to Portugal? Has anyone else been required to do this?
