We went to Skeggy Butlins at the start of the month for DDs 3rd birthday. Got an awesome deal, stayed in a fairground apartment, which was basic, but fine as a base. New Sky Park is really good and aimed more towards older kids, fairground has had a bit of a revamp, but not really any 'big' rides, although some good medium sized ones. Pool is awesome and wasn't really overly busy on either of the days we visited. The shows are definitely aimed at smaller kids, but there might be more on in the evenings? We were back at the room by 8pm every night. Arcades, like anywhere, will cost you a bomb.
Never been to Centre Parcs, but been on a few Forest Holidays pre DC, and unless they're keen cyclists, or you pay a fortune on the CP activities, they might get bored? If you do fancy that kind of thing though, FH Nottingham is right next to CP, there's a 'Go Ape' really close by, you can rent segways, bikes etc, and most of the lodges come with a hottub as standard, which is nice this time of year
Now, for Haven, we've done a few of these both as and with kids. We stayed at the Blue Dolphin at the end of summer, I'll be honest, more aimed at toddlers. But, Primrose Valley, that is close by, is a good park for teens. Location wise, it's awesome. You're close to Scarborough with the sea life centre, the arcades, a 'horror' house, an awesome park that's lit up beautifully with Chinese lanterns. You have Bridlington where you can go on a pirate ship around the bay, awesome indoor mini golf, fab fish and chips. There's Flamborough Head, Filey and you're close to both Dalby and Keldy Forest, which have some stunning walks and scenery. I might be biased, it's our neck of the woods, and not massively far out Skeggy driving wise
