My aunt, uncle and young cousins (aged 8 & 4) visited Legoland a few weeks back and had an absolutely wonderful time, so whatever problems the park may have might not necessarily be affecting the experience profoundly. When we spoke to them after they got back, they only had positive things to say about the experience!
I admit that I myself did not have the most pleasurable of experiences at Legoland when I visited in 2017, but I’m willing to admit that I would probably have enjoyed the park more if it hadn’t been for the circumstances in which I visited. It was very, very busy, which as someone who gets nervous around crowds, made me quite anxious when walking around the park, and my mum was in a wheelchair due to an ankle fracture and we had to wheel her around, which made things a lot harder for us as a family. To be fair on the park, I think I would have enjoyed it a lot more had I visited on a different day and my mum hadn’t had a broken ankle, and this visit was 3 years ago.
I’ve got to admit that the park itself actually seemed really nice for its target audience; very well themed, with a great ride lineup for its target audience, and excellent Lego models, and I must admit that even through an enthusiast lens, Dragon was a pleasant surprise (it was the only ride I rode there)! It’s a really long coaster, and for a family coaster, it was definitely more fun than expected!
