There is still a bin of bricks in the back of a closet in your house. Not because it is worth anything. Because every time you open the lid you are nine years old and the bedroom floor is a city only you understand.
Five zones take over the park for six weeks — Music, Creative, Chill-Out, a new Thrill zone, and a Play Zone built around LEGO Pokemon, the crossover that finally puts two entire childhoods on the same table. Kids build. Parents remember. Everyone disappears into something that requires no screen and no explanation.
The detail that gets parents: all of it is included with regular admission or an eligible annual pass. No upcharge, no premium tier, no wristband hustle. You walk in and the whole park is the festival.
Bring the grandparents. They will build something and be unreasonably proud of it, and you will keep that photograph forever.
