In reply to Cake: Depending on the age of your family, you can take them to Symonds Yat; you hop over the fence behind the tea shack and down the path to the crags while they enjoy the peregrines and the RSPB telescopes, lunch at the tea shack, and a jolly walk down through the forest to the bouncy bridge at the Biblins.
Then another day you can send them off to Clearwell Caves in the morning, and the Puzzlewood in the afternoon (and there's something across the road from the Puzzlewood for very small kiddies, I think); and there's a sculpture trail too I think somewhere in the woods. If they are a bit bigger you can send them (or you can all go) canoeing or horse-riding.
Have a lovely time!
