I am looking for an offer code I can use for gaining at least a 10%
discount (up to 25% may be available) when booking online at
http://www.centerparcs.co.uk

The criteria which must be met are:
Sherwood Forest
3 bedroom comfort plus or 3 bedroom executive
7 nights stay
Commencing on any of these dates:
Friday July 21st 2006
Friday July 28th 2006
Friday August 4th 2006
Friday August 11th 2006
Friday August 18th 2006
Friday August 25th 2006

Please note Center Parcs automatically apply a discount of 10% to all
7 night stays taken on the above dates (They add the 3 night stay and
4 night stays together and then deduct 10%). I am looking for an offer
code I can type in when I book that will give me an even larger
discount on top of the automatic discount (up to 25% is available).

There are plenty of offer codes floating around the internet, but
before you answer this question you will have to test the code by
going through the initial stages of an online booking, to ensure that
the code is valid and will save me money.
