It is lovely. Clean, nice families, loads to do in the local area. Gorgeous beaches. Highcliffe is the nicest imo. Empty and no tacky shops. Just sand. The site is scooter/bike/buggy friendly. Lots of nice playgrounds dotted about in between the caravans and chalets. The pool is great and has a lovely shallow bit which gradually gets deeper, like a beach iykwim. Ds and dd adore it. There is an outside pool too. They have a kids disco and games at 7pm each night and this is very popular.
As a child my parents had a mobile home there and used to go a lot. Now we take our dc's. We last went in Oct and ds is begging to go again in the summer.
I live there - (not the holiday park, obviously). Indian, Thai and Italian restaurants in village plus tearooms and coffee shops. Boat trips and crabbing at Keyhaven, good cycling if you're taking bikes. Lovely shops in Lymington. New Forest 10 minutes drive....Also, Shorefields now has an excellent spa
