I have visited Haven holidays with my family for the several years now, my favourite destination being Presthaven Sands Near Prestatyn.
This site opens in March and closes in November each year.
In Presthaven, as in most sites, they have a vast selection of entertainment, especially for the children, with different activities at each site.
It offers static caravans of various sizes and styles and also there is a place for touring caravans, situated near the Anchor pub, as you enter the site past the security gate.

Presthaven sands is easily found along the A548 in Gronant, (post code LL19 9TT), just outside the small seaside town of Prestatyn.
The actual site is situated a stones throw from the Denbighshire North Wales coast line, with it’s six miles of fantastic golden sands.

These are a little hit and miss with no heating in the bedrooms and the television is so small it comes free with a pair of binoculars, they are 10 feet wide and come with the basic of cooking essentials. 2 or 3 bedrooms to choose from.
The Standard plus models are 12 feet wide, slightly wider than then standard, but have the same basic interiors and contents.
With these modals you will have to hire bed linen from the linen store on arrival as it is not included in the overall price.
Both Standard and standards plus are the only modals to allow pets.

These have much more decorative interiors. The televisions are larger and come with either a video or DVD player.
The modals so far have no heating in the bedrooms, the only heat coming from a fire in the living room. Also smoking is allowed in the modals stated so far.

NOTE:

There are many Haven holiday caravan parks, all with basically the same forms of entertainment, restaurant, fast food outlets and fun parks.
At Presthaven, the caravans are situated in such a way that you are only a stone throw away from the sandy beech, which is a lovely walk into the entertainment centre on the park.
The other way to the entertainment centre is via the road which can be dangerous for the smaller kids, but the vast amount of speed bumps slow the cars down to a crawl.
The site hosts 2 indoor swimming pool, one for the kids and the learners, the other is more for the distance swimmer. A twirling chute drops you into the smaller pool with a bit of a splash. There is also an outdoor pool which tends to only open in the hotter days.
In the same building as the pool there is a large play area designed in such a way that the kids can safely play in the climbing area, filled with them little plastic balls and totally netted of so there can be no accidents. Whilst the parents sit around the café area to enjoy a nice well earned rest. Believe me the kids will love the climbing area, my two play in there for hours.

IN CONCLUSION...

The cost for a more luxurious caravans are a bit over the top, especially during peak season, but what you get from the site and the surrounding scenic areas make up for the cost. If you choose to take full advantage of the site facilities then you will not have to spend money doing so as all is included in the cost of your holidays.
A full day can be had with a swim in the morning, followed by a full English breakfast at the Mash and Barrel. Then a pleasant walk along the stretch of golden sands to either Talacre on the East, or West towards Rhyl.
Then maybe hire one of the many single seated tricycles to explore the entire site, but beware, these can be slightly tricky to manoeuvre, especially over the speed bumps.
For the more fearless, why not have a go on the small outdoor go-cart track, with the single or double seated go-carts....fantastically fast and funny.
In the afternoon you could chose to waste a bit of change in the arcade (which is situated in the entertainment centre, just passed the information desk), or maybe a drive out into the beautiful surroundings of north Wales.
In the evening there are shows for everyone, with Rory and Bradley for the young to Bingo for the not so young. With the entertainment changing each night and dependent on season.
