Lol i'm 26 never been to Legoland heading there in a few weeks you guys are putting me off though
It's a good park but unlike the other British parks it's not all about the rides. If you've never been before and you like Lego I can guaranty you'll spend hours looking around Miniland, the creation centre and all the little models around the park. There is also a core selection of rides that are good fun whatever age you are:
The Dragon, Wave Surfer, Atlantis, Pirate Falls, Viking's River Splash, Extreme Team Challenge (if you don't mind getting wet), The Mazes, Several transport rides with nice views and The Harbour Show.
But bear in mind it is a kids park. If you've neither a kid or interested in Lego then the park really isn't aimed at you.
