My son LOVES LEGOS and can't wait to go to the new LEGOLAND Discovery Center that is opening March 30th at Grapevine Mills Mall. They have discount tickets available until Sunday (assuming 3/20) for $12.50, plus tax, per person 3 years and older. I'm bummed that their regular prices are so pricey. For people age 13 and older, tickets cost $20.57 and for 12 and younger, tickets are 16.24. They do offer a LDC Unlimited Annual Pass for $48.71 per person or $184.04 for a Family Pass that's valid for any combination of four people. There is a perk for buying the LDC Unlimited Annual Pass. If you buy now, you can can visit LEGOLAND Discover Center on March 27th and 28th for days open exclusively for Pass holders.
