I only did the treasure tour so far. I have mixed feelings.
It is very well made, lots of details. Great for small children. I also love the effort they did on the outside to make the building seem smaller than it is.
But on the other hand, I found the inside too plasticy and 'merry'. Also, the little game/selection points might be nice for the people in the front seat, but it is just an annoying hold-up for the people in the back row.
In general, It is a high quality ride, but I prefer the more gritty rides like the flying dutchman and the Fata Morgana.
I would prefer if the Efteling sticks with its own darker fairytale style: nobody else does that like they do, while this ride looks like it could be in any Disney park.
