Our first time on the site and although we only had a couple of days here, we enjoyed our stay but cannot say that we experienced problems with the heating in the toilet block but we were closest to the one at the top of the site which was fine. First day the weather was beautiful and we went to the RSPB Hide at Snettisham (highly recommended but be prepared for a long and muddy walk from the car park). The second day we managed a walk around the Sandringham Estate Yellow route before the rain came down and boy did it rain!  Still, the site coped well enough and no lingering puddles that I could see. Overall, a good time for some decent family bonding.  We will be back hopefully when the weather is better.
