Hi Jemma
Well done . Here's to many enjoyable hols in the caravan.
Rather than listen to other people why don't you first of all surf the respective clubs web sites.
Choose a couple of locations / sites you fancy and try them out. A lot of the sites allow non members. That said the annual membership of both is relatively cheap and you'll recoup that cost in the first week away , plus you get their magazine.
Apart from their main sites they both have minor sites , Certificated Locations for CC & Certificated sites for C&CC. Most only allow 5 caravans and can have various levels of facilities. Some of the scenery at these places is fantastic.
Give them both a try this next 12 months and then you can tell us what you found.
Cheers
