. Sea Barn Farn, Weymouth, Dorset. (I've reviewed it). Has play park but no entertainment. Their sister site at the end of the drive has an outdoor pool and entertainment and was NOISY when we visited the pool. We were so glad to gl back to our quiet site. Our children were about 7, 5 & 1.5 (review may say actual age as i've forgotten).
. Willow Valley, Bude, Cornwall. Small site with play area. Went at Whitsun half term in 2015. Some children played on the grass in front of the tents (incl ours). Owners said fine for football. Huge pitches, some wooden picnic tables. Think i've done a review. Children were 9,7 & 3.
Look for sites without entertainment as they tend to be quieter and have the quieter types for evening and night times.
