OK....I think I have narrowed it down to
Hafan y mor (quite fancy Wales and the park looks to be pretty good).
Primrose Valley (Park looks fantastic...not convinced by area...but not really sure what there is to do round there)
Others on shortlist include Presthaven Sands; Seaview and Weymouth bay (I fancy the area; noty convinced by the parks).
Any comments on either the Parks or surrounding area appreciated. I have already been to Caistor; Burnham and Combe Haven...so those are definately out of the runing. Perran sands, Rivierre Sands and Rockley won't take Tesco vouchers so they are out of the running).
This is probably my last Haven holiday so I have to make the right choice
