The WTTC said the measures help to set clear expectations of what travellers can experience in the ‘new normal’ as travel restrictions are eased. The WTTC’s initiative is designed to avoid the emergence of multiple standards, which it said “would only confuse the consumer and delay the sector’s recovery”.

Among the recommendations for car hire firms are limits on the number of clients at vehicle collection, curbside pick up and drop off and enhanced cleaning of vehicles.

Attractions are to encourage guests to buy advanced tickets online if possible, and consider timed entries and smaller groups. Virtual queues, contactless touch points and a reduction in guests’ personal items are recommendations, while water parks are encouraged to remove interactive features that are not covered in treated pool water.

Short-term rentals are encouraged to use contactless technology at check-in and payment, deep cleaning and to provide guests with physical distancing advice.

Gloria Guevara, WTTC president and chief executive, said: “Worldwide attractions, car hire and short-term rentals all represent key components of many family holidays, so it’s vital we establish measures which allow safe travels to take place for holidaymakers and travellers.”
