The pass was designed to save visitors time and money in a bid to attract tourists to the country, which has struggled to bring in visitors as the war in neighbouring Syria rages on.

It was launched in September to serve as a “unified ticket” for independent travellers looking to visit the country’s most popular sights, including the Unesco World Heritage site of Wadi Rim and the ancient city of Petra. It combines the country’s visa fee of £37 with the Petra entrance fare of £47, as well as offering access to a number of other historical sites and museums.

However tourists have reportedly criticised the scheme, who said that staff at certain attractions and border points were unaware of its existence, The Telegraph said.

One traveller said she had been incorrectly charged £520 on attempting to buy the pass online.

A spokesperson from the Jordan Tourist Board (JTB) admitted to Telegraph Travel that it had received complaints about staff at sites not being aware of the pass, and apologised for the situation: “While the ministry did everything possible to communicate the Jordan Pass offering to all stakeholders, we still received complaints. Please be reassured that the minister himself is on top of this and we can confirm that such issues are now resolved.”

 The JTB added that there were plans to install Jordan Pass instructions in Arabic and English at the entry to each site, and at all Jordan’s border points, so that entry conditions were clear for everyone. It is also planning to provide telephone support for holders “in case they face any issues”.

They insisted that site staff and guides would benefit rather than lose out from the removal of cash interactions with tourists: “The specific income from the Jordan Pass is distributed among the sites to be used for enhancements including the pay of the employees there,” it said.
