Had a trip a few weeks ago for the first time in a few years and hated it.
I visited Legoland so much as a youngster, to go back and visit it later on and be so disappointed was a bit gutting.
Only a few rides are "up the the standard" in my opinion, and just too many rides and attractions aren't high enough capacity. (For the record, those rides are Viking River Splash, The Dragon and Fairy Tale Brook, maybe Atlantis.)
Atlantis would definitely have been if the ride didn't leave the second you started viewing the fish. (What was there was awesome, it just doesn't last anywhere near long enough)
Also I had never thought of Legoland as suffering from Merlin's lack of maintenance but it certainly does. Fairy Tale Brook (Still one of my favourite rides to be honest) looked absolutely dreadful. Nothing that should have moved did, everything looking as if it was about to break, everything needed a paint and it was a shadow of its former self. This was pretty evident all over the park to be honest.
Laser Raiders is one of the worst rides and queues I have ever experienced. What they were thinking putting such a low capacity ride in, is beyond me. Didn't see a single person come off the ride happy, even those that the ride is supposedly aimed at, and who can blame them after queueing ages for a such short ride with little substance.
It didn't help that all the trains in Miniland weren't working so there wasn't even anything to look at and entertain you there.
