Meg- um... no. Not Beauveland. Not in the field of pre-erected tents....Although it's entirely dependent on what sort of holiday you want, of course. We went there 2 summers ago, with TravelSmith to stay in a pre-erected tent.
The site is big; There's the small, crowded pre-erected section right up against the club-house and amenities block, and there are 2 or 3 big fields for bring your own campers. There's a reasonable kids playground and a large 'footy/kite flying' field. The club house has something 'on' every night; a band, bingo, karaoke etc etc, and shut down at 11 or 11.30pm, I think. You wouldn't want to be up by the club house- the closest tents were maybe 10 metres away- from amplified music, til 11.30pm. No. They do bog standard food.
The pool is small, old fashioned and cold!
The pre-erected tent itself was fine if a bit cheek-by-jowl with its identical neighbours, possibly 80 of them all up. Reasonably equipped (though, interestingly, no pillows supplied!). The tents and site in general were clean and well-kept.
The people from the 'DIY' fields were mainly European, well-dressed, well-behaved.
The clientele in the pre-set up 'TravelSmith' area was, frankly, appalling. Fat, loud, aggressive Sun reading northerners (sorry, but true), swilling lager and getting louder and louder as the evening wore on. Many, many tatts on show. No concept that they were living in a tent. When the bar closed, all the teenagers took to the children's playground and spent the next hour loudly trying to get into each other's fookin' pants. Followed by the toothbrush ballet..'Oi, Tyler, where's me fookin' toothbrush? Oi? OI?' etc. Our neighbours asked us to be quiet one afternoon, at 3pm, so (once again) their brood of under-dressed over-weight whining primary schoolers could 'get some sleep' on the mattresses pulled outside the tent, as they'd be up til gone midnight every single night. When they woke at 5pm, on went the ipod on speakers and stayed on til they went to the club house at 9pm. The children in the pool were aggravatingly loud, inconsiderate, aggressive and unsupervised, bombing into the pool from the low stone wall surrounding the pool enclosure.
It was horrible. And frankly, we were amazed that a site such as that down a country lane in Jersey attracted such people! We assume that, although it wan't cheap, it must've been cheaper than a package to the Costa del Sol.
Jersey was 'OK'. The beaches of the NE (where this site is located) were disappointing- the tide goes out miles revealing acres of craggy mudflat. The beaches of the SW and west were rather better, but a 10 mile drive away. We did a lot of driving around just to stay away from our dreadful accommodation, and so our DCs could get some sleep themselves, having been kept awake half the night by our moronic co-campers! I guess the truth is that if you live in a Birmingham council estate, Jersey must seem like paradise; whereas if you have Devon and Cornwall to compare it to, I'd go there instead any day.
Now, I believe the site owners (a family) have a few of their own ready-erected tents dotted around the DIY fields. They looked identical to the TravelSmith ones.
IF I haven't put you right off 
you might phone them direct and check the prices of those. I believe the whole 'experience' would be more tolerable miles away from the chavvy end of the site, as it ought to be lovely.
