We've been visiting Centerparcs for many years (we're still Select Guests which is the loyalty scheme from many years ago) and always found the restaurant prices to be slightly inflated but overall acceptable for what is effectively a captive audience. HOWEVER the 2012 price increases are absolutely disgusting - around 25% increase across the board.
A Steak in the Hugos country club is now £19!
A chicken curry main course in the Rajinda Pradesh restaurant is £15 - and doesn't include Rice and Naan (which adds another £6)!
Centerparcs, you are playing a very foolish game - taking advantage of customers who have no alternative is not the way to keep repeat customers coming back. This will be our last visit I'm afraid.
