Ok, first a small word of advice.
If you are planning a trip to Legoland, and you have a baby in your arms, Don't! The place is huge, requires walking around a lot, and standing in queues for largish periods, and there's usually nothing for the li'l one to do. Having said that, if you have a 5-12 year-old, please do visit this wonderland. Please keep 2 days to be able to explore it fully, and really have an enjoyable experience.
Please also carry loads of eatables & a few cans of whatever liquid your youngster (& you) are hooked on! Standing in a queue for 25 mins at the Burger ranch, while Johnny Thunder & his Flying Adventurers start their show in the background, is likely to cause you a whole lotta grief!
That said, it was a good trip. Something the kids are likely to remember for a long time to come (hopefully!) And we adults didn't get too bored! Some photos below:
