Whoever designed the space did a TERRIBLE job! Most attractions are only for children, which leaves crowds of adults standing around in tiny spaces waiting for their kids. There is not nearly enough seating so if you don't mind standing around- in awkwardly over-crowded spaces- this is the place for you!
Now let's talk about the Legos. Go visit a Lego store and your kid will have more fun, plus the stores are free to walk into- unlike this place. The Princess Palace is a joke. There are 3 lego tables with about 20 large legos at each one. Then there's a stage with a karaoke screen- so if your toddler can read it might hold their attention for a few minutes. Otherwise, the Princess Palace is a total waste of time.
The space where kids design their own lego cars and race them is extremely small and overcrowded. Be prepared to lose sight of your child on a constant basis and then not be able to squeeze through the hoardes of people standing around waiting when your child runs off through a small break in the crowd.
The kids all had fun, but for the adults it was a bit of a nightmare. Definitely not worth the price to ever go again.
