Just added info on Legoland's Brick-or-Treat to our Professional Haunts page. This might be a good one if you have young kids, but it is a bit of a drive for Los Angeles Halloween Haunters, down the 5 Freeway all the way to Carlsbad.
On October 13, 20, and 27, there will be a Costume Celebration, with Brick-or-Treat Trail (a kid-sized cul-de-sac featuring LEGO-themed Treat Stations) set aside for kids to trick-or-treat .
There is also "Brick or Treat After Dark." On Octobr 13, 20, and 27, the park stays open until 8:00pm with Halloween-style fun: a candy Corn scavenger Hunt at Huanted Hideaways, a LEGO brick pumpkin build, and a nighttime costuem contest for best "after dark" costume.
