We went, and I'm in two minds. It's basically an expensive day trip and it doesn't compare to the real Lapland. However it is sweet and well-organised, and a good day out. My 6 year old said "Is this fake snow?" as soon as we got in. It's not cold or wet - it looks pretty but obviously fake. So I think it would be hard to convince an older child that it was real.
I do think both my children believed they saw the real Santa - by far the best I have ever seen, and in a lovely little log cabin in the woods with no-one else in sight (except an elf with a digital camera set-up!). However he did not mention any of the personal details we had given about my children, their hobbies, likes, friends etc. Very disappointed as this is one of the main reasons we booked. We thought they'd love it and talk about it for months after - how he knew so much about them, but he didn't say anything personal. I e-mailed to complain afterwards and just got an e-mail back saying sorry, we don't know how that happened. They could have sent a little personal note saying Father Christmas had loved seeing them or something. In the end, we did that ourselves.
It's basically, a wood with Christmas trees covered in fake snow. The staff are friendly, you don't feel rushed. It's not packed and unpleassant - probably not at those prices! There's a series of activities - making rocking horses (bit rubbish - just putting pieces together), decorating gingerbread, lunch and Santa visit, followed by ice-skating. However the ice-skating's not for under-4s and my two hated it!
We were there from 11 to 4 so we had a good day out, but very pricey and definitely NOT the real Lapland.
