Hi Pat - I presume you're using Camping Cheques, or an ACSI Card. If the first, then Ma Prairie at Canet en Rouisillon is highly recommended, as is Le Haras at Palau del Vidre. We also like Camping Neptune at Grau d'Agde - though recently it has become busier in low season, and we do tend to like big sites, but only when they're quiet!
If you're looking for a site with slides/etc then Domaine de Champs Blanc (Camping Cheques) has them, and a large pool complex which resembles that at Les Vagues. Pitches are somewhat shady, though, in places, and you may find there is some road noise. Les Vagues doesn't get good reviews on a lot of review sites which I've read.
With ACSI you've a choice of sites - though we haven't stayed at any in that area. Domaine de la Dragonniere is a big site, with several pools, and a lively bar and restaurant(s). Camping le Californie Plage at Vias was recommended to us by people we met this year.
