I know Im in the minority, as the rest of Britain seems to love Centre Parcs (and to be fair my kids loved it) but me and DH hated it!
Our main gripe was the accomodation - ewwwwwwwwwwwwwwww. Totally gross - like living in an outside toilet. Damp, mouldy walls, torn furniture, tiny rooms. Horrid. Ive been told that the "executive" accomodation is fine, but when I costed that recently it came at over £1K for a WEEKEND!!!!
Second, everything extra costs big bucks - except the pool which was so packed jammed solid the kids were scared to use it. They kept getting pushed off the slides by older children and you couldnt "swim" because of the amount of people in the pool. We thought £6 to hire a badminton court for 30 mins was ridiculous.
The car parking was a joke, the shops shut at 7pm so if you ran out of anything - tough. The food was expensive and very poor (with the exception of the Indian restaurant which we liked). DH was mown down twice by lunatics on bikes and We also saw one stupid woman knock a toddler over because she was going too fast and chatting to her family behind.
The only thing we did rate were the staff - obviously all students, they did their best with everything and you always got a smile.
I couldnt bear to stay in one of their minging "villas" ever again, even though the kids pester us endlessly to take them back!
Sorry, nil points from us. Oh and it was Eleveden we stayed at.
) There is a great spa. There are loads of activities to do but you must book them as they get booked up very quickly. 
, and it get's really really busy. But we still love it, almost as much as WDW
