Brea in Orange County.
Perhaps there is something in Anaheim Hills, but I don t know exactly where that is. However, I DO know of Eagle Hills in Brea, where people are NUTTY about Christmas. They spend months trying to out-do each other. The whole neighborhood is LIT UP like Vegas. Haven t seen anything like this since the old days at Hastings Ranch in Pasadena. Take the 57 freeway to Lambert, and go EAST (away from State College Blvd). When you pass Kraemer, look for the signal at Sunflower and turn right (IF you can... the line of cars to get in can be long). Don t enter from Birch St, it takes 30 minutes to get in from that side. Lots of streets and houses to see, usually takes us about an hour.
Idk about Orange County but there is one in Chino, Ca that I have been to that goes for blocks (I think you have to walk or they pay for you to drive through it... I m not sure... but it s better to walk)... they sell hot chocolate... tamales... and have a ton of cool houses... just prepare for a little bit of a walk... don t wear heels!
