Yes we've been to Ord House. We've used it a few time as a stop off on our way south when we used to leave for holidays straight after work. It's fairly big and there are a number of statics. Very nice pub/restaurant in the old house on site. There was a good shop including accessories when we were there last too. I would recommend it if you like family sites. Once we were given a pitch in the walled garden and I liked that best - it was quiet. Lovely area - Berwick is a pleasant town and there are some great walks nearby.
We stayed at Ord House in January last year and would agree with all Mags52 said and would add - it also has a bath.
Have also stayed at all the Camping in the Forest sites in Scotland and all have been grand - Glenmore I wouldn't visit in the height of the summer - too busy and the facilities struggle, but fine the rest of the year.
Thanks for the heads up. Off for 2weeks as work in a school, will try and have couple of nights there. Should be worth it x x
