No hairdryers so take one if you need one.
We find hiring a golf buggy makes everything that little bit easier - but there is a bus too.
The included cot is usually a travel cot in the wardrobe so don't panic when you don't see one set up in a bedroom!
Onsite food in the village is ok - but the Wildwood cafe in the adventure centre at the top of the site is really good - and I have heard good things about the kids tea time show there.
They sometimes run out of highchairs in the main restaurant so if you have a travel highchair type thing that's easy to pack, that might be useful.
No free flotation vests in the swimming pool unlike CP.
They have a milk, cheese and butter vending machine in the village that you can use after the shop is shut!
A small welcome pack is included with dishwasher tablets, a wee bottle of washing up liquid, a wash up sponge, a tea towel and bin bags - which might be enough for a short stay.
Take a torch too. And sharp knives if you need them.
And if you have the energy, then there are loads of great places to visit nearby: Tenby, Folly Farm, National Trust Stackpole Estate, Saundersfoot and more. The Village Central information point will have info too.
