hello
we have been to all three and enjoyed all three
butlins is very full on and noisy, I personally couldnt do a full week there. Hotel is nice, cheaper accomodation could do with updating. There is lots which is free if you just avoid the amusements and gift shops. Half board is quite good value if a bit school dinnery. Loads to do in evening if you like shows etc. Swimming pools open reasonabl hours. Some outdoor play, free fairground inside (kiddies) and outside (bigger rides) Huge soft play area inside.
haven is caravans mainly which vary in comfort. This was a quite relaixng family holiday. again, lots of amusements but also all entertainment is free and so can work out a good cheap holiday. Swimming pools open quite restricted hours. Normally have a playground but kinda limited, our last one had a small softplay in the corner of a bar which was out of order (apparently, had been for months on end)
Center parcs has lovely big comfortable accomodation. Pool beats the others hands down as is open 12 hours a day. But, everything else costs eg bikes, evening entrertainment, activities etc. There is nothing on in the evening really unless you go out for a meal or pay to see a show or pay to go bowling. But, the pool is open to 10pm and also your accomodation is so comfortable and peaceful that you can sit in of an evening. Fabulous outside playareas for children, massive and suitable for variosu ages. Also, have good softplay.
If I had the choice, I would go center parcs every time, but I do enjoy the others too, and the fact they are A LOT cheaper hel.ps too
