Cardiff Blues are encouraging their army of supporters to descend on BT Sport Cardiff Arms Park before and after Saturday's Judgement Day clash with the Ospreys.
More than 65,000 tickets have already been snapped up for the Principality Stadium double header and it promises to be an electric atmosphere.
The Gareth Edwards lounge, on the top floor of the clubhouse, will be open to all from 11.30am and there will be live music outside post match.
Danny Wilson’s men will also return to BT Sport Cardiff Arms Park following their encounter with the Ospreys.
So why not get in the spirit and hopefully toast a victory at the home of Cardiff Blues.
Our club shop and ticket office will be open as usual while we will also have merchandise points both inside and outside the Principality Stadium at Gate 3.
All jerseys will be available at the bargain price of £10!
With so many visitors flocking to the city centre, supporters are urged to arrive no later than 30 minutes before the matches; Cardiff Blues versus Ospreys at 2.30pm and Newport Gwent Dragons versus Scarlets at 5pm.
Supporters are also advised to leave large bags at home where possible or expect to be searched, due to enhanced security measures at the iconic venue.
The WRU joins forces with Cardiff Council and city travel operators to ensure fans get the relevant information ahead of major events. Details and further information are available here:
Principality Stadium Manager Mark Williams said: “The buzz around Judgement Day IV is huge, with more than 62,000 tickets sold to Welsh rugby fans, and so we know that Cardiff is going to very busy on matchday.
“As with any event at Principality Stadium, our message to the supporters is to plan in advance.
“It is of course fantastic news for the WRU, the four regions, all the players and supporters that the attendance and atmosphere in the stadium will be up there with that of an international match on Saturday.
“With this comes a serious message to fans travelling to the match that Cardiff and the transport infrastructure will be busy and planning ahead is necessary to ensure they don’t miss out on what will be a great day of rugby at Principality Stadium to celebrate Judgement Day IV.”
