We have stayed at Cherry Tree Caravan park for several successive years. Used to be run by Parkdean Holidays, bought out by Haven, but going back under Parkdean ownership for 2005.
Nice park - not all squashed like Sardines as some are, indoor and outdoor pool, bar, restaurant, decent shop, launderette, amusement arcade, kids play area, crazy golf. 15mins from Gt Yarmouth (bus-stop if required immediately outside park entrance). Can't find a website , but their phone number is 01493 780229.
Not sure what, if any, the changes will be for next year - but we actually used to prefer it under Parkdean management, so are hopeful.......
