As winners of the Europa Cup, United will play Champions League winners Real Madrid at the Phillip II Arena in the Macedonian capital city of Skopje on Tuesday 8 August.
But fans – many of whom booked hotel rooms months ago in anticipation of their team winning the Europa Cup – are outraged after hotels in Skopje suddenly increased their prices.
Angry supporters complain that hotels are demanding an extra 500 to 900 GBP – per night – to honour the reservations, according to local media reports quoting TV 24, who say they have spoken with fans by phone and have taken statements from them.
Football fans in Skopje are also unhappy that hotels are trying to fleece supporters and are offering to let them stay in their own homes instead.
Manchester United fan Nick Horn said: “Many United fans booked hotel rooms months ago, hoping that we would play in Skopje.
“Now, they are not respecting the reservations. Hotels are asking us to pay extra money, because the reservations were made a long time ago. The fans were told that they cannot use the rooms, because they have to pay more.
“The good news is that there are many good people in Macedonia offering their apartments to UK Manchester fans.”
Joseph Drain, another Man United fan, said supporters could not believe they were being asked to shell out hundreds more on rooms they had already booked at an agreed price.
He said: “That is a lot of money. We have never spent so much money on hotels and we have been to many countries. This is scandalous.
“People have been given different reasons why their hotel reservations have been cancelled. One of the reasons one hotel management mentioned was potential terrorist attack.”
Officials who monitor hotel prices in Skopje said that they were unable to investigate as no football fans had complained to them about the price hikes.
The controversy is also reportedly affecting fans of Real Madrid who also pre-booked hotel rooms.
The Macedonian government has said that it expects bars, restaurants and hotels in Skopje to conduct themselves with “dignity” in the way they deal with visiting football fans.
They are also cracking down on touts who are believed to have picked up a significant number of tickets for the Super Cup in the hope of selling them to fans at a huge profit.
Touts have been warned that they face huge fines, and possibly even prison sentences, if they are caught illegally selling tickets.
Both Manchester United and Real Madrid are expected to take around 10,000 fans to Skopje for the match.
Some, scared off by high prices of 240 to 520 EUR (211 to 475 GBP) per night quoted by local hotels are planning to stay in neighbouring Bulgaria or Greece and travel to and from Skopje for the match.
