Hotel rooms around Cardiff have almost quadrupled in price for fans hoping to see the Ireland clash with France in the Rugby World Cup.
Supporters are now being urged to book their flights and accommodation early for the October clash as the demand sees prices escalating.
Ireland have been drawn against Canada in Cardiff on September 19, and Romania on September 27.
But the games that will produce most interest are the clashes with Italy in London's Wembley Arena on October 4 and France in Cardiff on October 11.
With options for fans in London being relatively plentiful, the pressure on prices there has not been too strong.
But the game against France in smaller Cardiff, however, has seen a shocking jump in prices, especially in some of the hotels.
The Holiday Inn website shows its City Centre and Cardiff Bay hotels are now sold out on October 10, but its North M4 hotel on the outskirts of Cardiff is charging £360 (€480) for one adult.
The same room a Saturday night in February would cost just £75 (€100), representing a 380pc increase on the night before the big game.
The three Marriott hotels closest to the Cardiff grounds are sold out for October 10, but the one in Swansea 34 miles away is charging £229 (€306) for that night.
The same room on a Saturday next month would only cost £116 (€155), and one in the centre of Cardiff would be £109 (€146).
The Hilton Hotel in Cardiff is sold out on October 10, as are its hotels in surrounding towns.
A Ryanair flight to Cardiff the day before the game with France on October 11 will set you back €153.99, with a flight home on the day after the game costing just €31.99.
Ryanair does not routinely fly to Cardiff.
Aer Lingus is charging €138.89 for a flight to Cardiff the day before the game with France.
The same flight a week earlier would cost just €43.
The return-leg of the same Cardiff trip on the day after the game costs €172.39, according to the Aer Lingus website.
The same trip a week earlier costs just €53.
Killester Travel, who set up packages for sporting events, said it has chartered planes to cover the Rugby World Cup, and has had to book hotels for the France game in other towns including Swansea and Chepstow.
"The hotel prices were just outrageous in Cardiff, except for the Maldron which seemed to price responsibly and is sold out," said Paddy Baird.
"So we booked in surrounding towns and we will bus our clients to and from," he added.
