The call: It’s mainly a giant LEGO showcase plus hands-on building—good for your 2-year-old if he enjoys colorful vehicles and characters, but I’d plan on 60–90 minutes, not the full three-hour session.

Real-time local factors

• Professional LEGO artists and local builders display large custom creations.
• Kids can build in communal brick pits and explore the local-builder fan zone.
• There are meet-and-greets with LEGO creators and “LEGO celebrities.”
• Vendors sell LEGO sets, minifigures, pieces and collectibles.
• It’s advertised for all ages; children 2 and younger are free. Stay close in building areas because of small pieces.
• A portion of proceeds supports the Build Smiles Foundation, which provides LEGO sets to children in need. Event details

Runners-up

• Choose the 10 a.m. session if your son does best before lunch and naps.
• Choose 2 p.m. if mornings are difficult, though the session may overlap with nap time.
• Skip it this year if he mainly wants oversized toddler blocks—the event emphasizes regular LEGO and detailed displays.

What flips this: If he frequently puts small objects in his mouth, I’d treat it as a look-only outing or wait until he’s older.

👉 Would Saturday or Sunday work better for you so I can check which session still has tickets?
