Primrose valley for teenager

[NeverAloneNeverAgain]

We're looking at primrose valley for a holiday next year but have a big age gap (youngest is 3 and next one up is 15). We can't go abroad as unfortunately youngest has some health issues which means currently we need to stay relatively local. Obviously its DS15 holiday too and we need to make sure there's things for him. Anyone have any experience of older children at haven or any alternatives so our older ones can enjoy their holiday and not be bored senseless?

Would it be possible for him to bring a friend, then they could hang out at the park/arcade, go swimming etc without always having to have the little one tagging along?

We went this year with my 8 year old DD and 13 year old DS. There’s no WiFi apart from in the main building so my
two were absolutely bored stiff any time we were in the caravan. Only activity my 13yo enjoyed was swimming. Definitely take a friend for your son if you can or he’ll be bored and fed up. I would say a lot of the activities are aimed at younger kids.

Thank you! Feel embarrassed I hadn't thought of that. Could be the best solution
