FA cup finalists can no longer battle it out to stay in the "luckiest" hotel.
The Vale: A star less than St David's but the clear favourite
The Football Association says teams must now toss a coin to decide which team will go where out of the two hotels it has chosen this year.
The venues - St David's Hotel and Spa in Cardiff and the Vale of Glamorgan Hotel - are likely to see teams up in arms over who stays in the latter.
The Vale has earned a coveted "lucky" reputation because only one team that has stayed there has ever lost a game.
This only happened last month when Bolton were defeated by Middlesbrough in the Worthington Cup Final.
The new rules, suggested after rows over last year's hotel bookings, mean accommodation will now be chosen in the same way as dressing rooms and team colours.
St David's Hotel and Spa has seen a losing streak for football teams who have stayed there.
A Feng Shui practitioner visited the five-star hotel in August, to try to lift the hotel's apparent football curse.
He scattered incense and sea salt, rang bells, chanting a Buddhist ritual and led a horse around the grounds.
Rugby teams, however, have fared better there.
The England team recently stayed there before going on to win the World Cup.
Arsenal stayed at the Vale of Glamorgan before the last two FA cup deciders.
But Saturday's action has ruled that team out of having to choose heads or tails for the first time this year.
That decision will now fall to Millwall and Manchester United before the final at the climax to the competition at the Millennium Stadium in Cardiff.
