Kurt Janson, director of the Tourism Alliance, gave a presentation on the latest impacts of Brexit at the Antor Annual Review.
He said the full impact of the UK leaving the EU remains unclear until a deal is negotiated.
In regard to immigration policy and issues, such as tourist visas for UK citizens visiting the EU and vice versa, Jason said "everything is on the table". It will, however, be "business as usual" for tourism between the UK and Ireland as the Common Travel Area agreement remains in place.
For British tourists visiting the EU, Janson said travel will become "more complex", with travellers requiring international driving permits, pet passports required for anyone who wants to travel to Europe with their domestic animals, and health insurance as an added cost once UK citizens can no longer use the European Health Insurance Card.
However, the good news is that there are agreements in place which mean aviation should remain unaffected and flights will not be grounded. For ferry and road passengers, there could be delays at ports and in the Channel tunnel.
Janson said that for agents selling holidays to non-EU destinations, Brexit could represent an opportunity. Turkey is benefiting from Brexit with the pound sterling strong against the Turkish lira. Egypt and Tunisia, which are experiencing a renaissance after some difficult years, are also expected to benefit.
