we went to butlins skegness last september with DS who was 2.4 at the time.
I was abit worried before as i read some shocking reviews but it was one of the best holidays i've ever had!!
We went monday- friday and didn't need to leave butlins the whole time.
What i liked is that although it was bit more expensive than Haven there is alot more included in the price. There is a little kids fair with four rides(bob the builders yard) which was free so that meant DS didn't hassle us over going on the rides in the arcades which are about 50p or £1 a time and could get pricy.
The swimming pool was being upgraded last year so alot of it was shut but when the new bit opens should be great, i think it opens half term 2013.
DS isn't really into the shows yet so we didn't really watch them except one mike the knight show when he was tired after swimming and tied into the pushchair!
There is a pub called the sun and moon which we liked as it has two climbing frames in the garden.
I wasn't overly keen on the softplay, although we only went there once for about 15 mins as we got there just before it closed for lunch. It is in an arcade and justs seems abit more chavy than other things.
The section of beach that runs along side Butlins is really nice, also where you go up to the beach there is a giant beach which is for photos- giant deckchair, umbrealla etc and at the bottom of this is a big sandpit, DS liked playing in this.
We had the food option, we only had the standard but i thought the food was lovely. It was quite busy but you didn't really have to queue for food.
We have booked to go minehead in May and are also prob going to book another break at Skegness in Sept.
The only thing i am bit wary of though is that we had a fantastic week weather wise, in fact i think it was the only good week of the summer. If weather wasn't so good then not sure what it would be like, there is plenty to do indoors but it would mean everyone would be doing indoor stuff so more cramped.
DS now 2.8 still talks about Butlins and sometimes says 'can we go to butlins today' so it def left a good impression on him
We booked basic accomdation but got umgraded to silver (we were room only due to booking half board). Chalet had a small hall way then a bathroom with shower, two bedrooms one with double and one with twin, both rooms were a decent size and both had TVs.
