The new regulations, which extend to rental properties and campsites, will require businesses to handle a variety of data, including contact numbers and the number of guests. Failure to comply may result in heavy fines ranging from €100 to €30,000. The Confederation of Spanish Hoteliers has voiced significant concerns regarding the burdens these changes place on tourism, considering legal action to contest the rules. The adjustments have raised fears about long lines at check-in, as the processes might become cumbersome for travelers seeking a swift start to their holidays.

To mitigate potential delays, many businesses are expected to move towards automated data collection. Yet, industry experts warn that the updated requirements could confuse travelers and degrade their accommodation experience. Although critics of the changes acknowledge that much of the requested information is already collected, they argue that the intensity and complexity of the new regulations could dissuade last-minute bookings.

As Spain welcomes a record number of tourists—82 million in 2023—the introduction of these extensive documentation protocols adds another layer of complexity to the travel experience in one of Europe's top destinations. The situation remains fluid as stakeholders adjust to the impending changes, with travelers advised to stay informed about how these new policies may impact their journeys.
