For what its worth, Carne's in season green fee is 65 euro. 90 euro gets you the entire day.
I think that's a fair price.
In truth, the most I ever paid for Carne, in June, on a weekend, was 30 Euros a game. The club having been desperate to collect money for the new 9 and the clubhouse have run deals these past several years if you pay in advance. At 60 Euros, Carne is a bargain. At 30, its an absolute no-brainer.
