One thing I've noticed about Legoland is they seem to be stricter on health and safety rules than a lot of other parks. Now I have no objections whatsoever to a park ensuring peoples safety, it's what you'd expect a park to do. In this case though I feel there are occasions where there's more concern about adhering to the letter of the guidelines, rather than adhering to what makes common sense. On this ride for example it says it must always be 2 people per raft. Now it makes sense when you've go a small child you don't want to go down unaccompanied, and I can see why they'd want to keep the rides capacity to a maximum, but when on a quiet day when there's no queue two large adults that you'd think would get a raft each, like you do at almost every other raft ride at any other park I've been to, but not here, no. Instead you have to adopt a very awkward position I wouldn't be surprised to see in the Karma Sutra just to fit inside a raft. There's also the question of what a group of an odd number is supposed to do, apart from having to queue up twice leaving someone behind each time.

My advice would be just to skip this ride if you have an odd numbered group. Although the ride looks pretty good, being set nicely in the side of the hill with some nice theming, once you're on the ride it's pretty standard stuff. You loose the initial acceleration from the station pretty quickly, and from there the ride feels like it's just going through the motions. I'd only do this ride again if it was a quiet day and the ride was a almost walk on. It's not one that justifies a long queue.
