Ok, I need some help! I'm planning on taking my three sons, 16,13,12 on vacation to Southern California. We have most of the trip scheduled with one day left and we're looking at either Magic Mountain or Knotts Berry Farm. The oldest loves rollercoasters, the two younger ones aren't sure if they do or don't (dont you love kids!). We did Six Flags in San Antonio and they loved it. Any opinions/Help?
