More likely to be €100 diesel in the Range Rover and two nights in the Westbury based on my (admittedly amateur) profiling of many of those who sit beside me at the rugby!
Lets not lose sight of the issue, the IRFU are bogging the arm in, because they can. They have built up a huge potential international fanbase which is now, as a result of the success of the team (that old Irish chesnut as Macy pointed out) and the larger size of Croker, too large to be accomodated at Lansdowne.
What do you do when demand outstrips supply? You increase prices.
Ireland are currently in the bizarre situation that they can't cater for the demand to attend at either international or provincial level. Yet outside of tag rugby, adult playing population has fallen quite a lot. If generating more revenue allows the IRFU to keep the international teams and provinces competitive, pays back the debt AND allows grassroots investment to grow the playing base, then its a no brainer IMO.
And as Macy said, if you can only afford one or two games, share. I know lots of people who informally do this (and do it for FAI block bookings also).
